Botletics SIM7000 LTE CAT-M1/NB-IoT Shield for Arduino

Overview

This shield uses SIMCOM's SIM7000-series module, a low-power cellular module that supports LTE CAT-M1 and NB-IoT technology and integrated multi-GNSS (GPS, GLONASS and BeiDou/Compass, Galileo, QZSS standards) for location tracking. The shield can be used in different regions around the world by using the appropriate module version: SIM7000A (America), SIM7000C (China), SIM7000E (Europe), or SIM7000G (Global) as detailed on the Github wiki. The shield also includes a high-accuracy I2C temperature sensor for IoT monitoring applications. To use the shield, follow the step-by-step wiki to attach the headers, plug the shield into an Arduino, insert a compatible SIM card, attach the dual LTE/GPS antenna, and you're ready to load the example code!

You can buy the shield on Amazon.com.

Check out the comprehensive wiki or use this Instructables to get started if that works better for you!

sim7000-lte-shield's Issues

Adafruit_MCP9808

I am getting this error for Adafruit_MCP9808.h: No such file or directory.

Compilation terminated.

I have added the MQTT library as well.

Couldn't find FONA

I added the library and I uploaded the library but now I have another issue in the port monitor : Couldn't find FONA
I am using Hologram Sim card

Firmware using in SIM7000A

Could I ask what is the firmware version use in the SIM7000A module?
Where could I download it? Thanks

Intermittent PWR issue

The board seems to intermittently reset the power and the PWR LED on your sim7000A board board goes off. I am sometimes able to get the chip to connect to the verizon hologram network and issues the n or 1 command in the LTE_demo example. Sometimes I get ctreg 0,2 which is searching. But eventually the PWR LED resets and I am unable to get any further responses from AT commands until I hit the reset button on the arduino mega 2650 board to establish a connection with it again. When it connects to the network it seems to be pretty stable for a while, until I issue the G command for gprs. It then gets to the SAPBR command, or sometimes as far as this:
---> AT+SAPBR=1,1
<--- OK
---> AT+CIICR
<--- +PDP: DEACT
But then the power resets and I am stuck unable to get a response again. When I first tried this a week ago I was able to reach the internet once or twice, after many failed attempts. I did not edit any of the code. I'm connected by USB power. The antenna is connected correctly and I have good signal. Any ideas?

Does it work for 5320E ?

It seem that can not enable 3G for 5320E ?

No PPP on UART with B05

Hi,

Just tried the B05 firmware but couldn't setup PPP over UART anymore:

-> AT+CGREG?
<- OK
-> AT+CGATT?
<- ..+CGATT: 1....OK..
-> AT+CPSI?.
<- +CPSI: LTE CAT-M1,Online,240-XX,0x0086,7681025,0,EUTRAN-BAND1,1925,2,2,0,0,125,0 OK
-> AT+CGPADDR.
<-  +CGPADDR: 1,10.41.136.51 OK
-> AT+CGNAPN.
<- +CGNAPN: 1,"xxx.com.xx" OK
-> ATD*99***1#.
<- ERROR

I had to downgrade to B03 again:

-> ATD*99***1#.
<- CONNECT 150000000

And PPP over UART works fine again. Any ideas?

What is the Reset PIN?

Add support to upload firmware properly to solve IMEI issue

Hi,

First of all I would like to say your project is great, I love it. Here is some experience I did some firmware upgrade and I would like to share it.

I remembered I bought SIM7000E module before June 2017 and the module firmware is not very updated. So many AT command stated in manual can't be used. Been followed your guide on firmware update tool, I found that IMEI on module was missing after firmware upgrade.

To solve this, you will need restore QCN file attached follow the instruction under section How to update xQCN file if necessary in How to update SIM7000 FW version with QPST.pdf. The QCN file is standard and works for all SIM7000 series. Then run AT+SIMEI=your IMEI number. You can find IMEI number on top of SIM7000 module. Hope it helps.

MDM9206_SIM7000E_P1.02_20180118.xqcn.zip

** Better to confirm with SIMCOM engineer if the file works for all SIM7000.

Failed to enable GPRS

My previous issue was resolved. I was missing a library.
After uploading the IoT_example code, and changing the APN to match our providers APN, the system is trying to enable GPRS but fails. Keep so retrying.

How point out problem by at commands?

I am testing "SIM7XXX_LTE_Demo", but unfortunately, In my environment, "[2] Post to dweet.io via LTE CAT-M / NB-IoT (SIM70000)" returns error code 601.
It seems network error, so I used AT commands to find out the reason, but I couldn't find out yet.
It seems on roaming network, but IP function couldn't work. What I should try next ?

Multiband LTE Module Support

Any chance you could put a quick design for SIM7600E or similar modules like SIM7100? Would be very grateful. I guess the current pin-out may not support direct replacement.

Thanks

GPS/GNS for SIM7000

Hi,

SIM7000 units use GNS AT commands as per the manual. I know AT+CGPSPWR? mysteriously works on the 7000 at the moment but it might be worth changing enableGPS to this:

`boolean Adafruit_FONA::enableGPS(boolean onoff) {
uint16_t state;

// first check if its already on or off

if (_type == FONA808_V2 || _type == FONA_LTE_A || _type == FONA_LTE_C || _type == FONA_LTE_E) {
if (! sendParseReply(F("AT+CGNSPWR?"), F("+CGNSPWR: "), &state) )
return false;
} else {
if (! sendParseReply(F("AT+CGPSPWR?"), F("+CGPSPWR: "), &state))
return false;
}

if (onoff && !state) {
if (_type == FONA808_V2 || _type == FONA_LTE_A || _type == FONA_LTE_C || _type == FONA_LTE_E) {
if (! sendCheckReply(F("AT+CGNSPWR=1"), ok_reply)) // try GNS command
return false;
} else {
if (! sendCheckReply(F("AT+CGPSPWR=1"), ok_reply))
return false;
}
} else if (!onoff && state) {
if (_type == FONA808_V2 || _type == FONA_LTE_A || _type == FONA_LTE_C || _type == FONA_LTE_E) {
if (! sendCheckReply(F("AT+CGNSPWR=0"), ok_reply)) // try GNS command
return false;
} else {
if (! sendCheckReply(F("AT+CGPSPWR=0"), ok_reply))
return false;
}
}
return true;
}`

Program memory requires more please reduce

Sir good evening
I run the IoT example everything is great but the Arduino Uno r3 has 32kb of ROM and 2kb of RAM and the IoT example requires 80% of ROM and 81% of RAM so that I get a problem because I want to embade the impact sensor to detect the accident but because of memory I can't embade
Please reduce down the memory requirement by that I can connect extra sensor and improve my project
Sir if it possible than try please thanks

Library compatible with SIM5320A?

Hi all,

I am trying to make a diy 3G cellular data logger for my school project, I'm using a TinySine 3G/GSM/GPS module with an Arduino UNO and an AT&T sim card. I keep getting:

AT+HTTPTERM
ERROR
AT+HTTPINIT

I used the Adafruit library and this one uploaded here, but keep getting the same results. Could you please help?
Thank you,

Adafruit_Fona_LTE does not name a type

I am trying the tutorial on https://www.hackster.io/botletics/real-time-2g-3g-lte-arduino-gps-tracker-iot-dashboard-01d471
when I try to upload the Iot_Example to the arduino I get this error:
Adafruit_FONA_LTE does not name a type
how can I fix this probleme
I am new to arduino

Close (but no cigar!)

Hi!
Im using the TinySine SIM5320A shield on a Uno board.
I removed old versions of the Fona Library and downloaded your latest one from github yesterday(8/24/18).
I changed the #define to SIMCOM_3G.
I updated the APN info since I'm using an AT&T sim card that belongs to a spare (working)phone I have.
It compiled and uploaded fine and ran, can turn on GPRS, can check the network etc, but I just can't get the dweet to work. I think I'm really close.

See the Serial output below.

Any words of wisdom you can share?

7000E firmware

Hi,
Which firmware version are you using for these examples? Some of the AT commands specified does not work on my SIM7000E.

Firmware update failed

Hello,

I have installed all the drivers, no unknown devices appear in Windows Device Manager.
I also followed upgrade instructions step by step, checked everything few times but I still can't manage to update due to "ConnectServer failed1, Please repower 1 DUT" error.

Firmware Versions

The firmware folder doesn't have a version for the SIM7000A, do you have any?
I tried to reach out to Simcom without luck.

The modem I have is facing issues sending SMS when connected to Verison network directly, but it can establish a connection over Http.

appreciate your help

Garbled output, what could be the cause?

After taking my fully working project apart and reassembling it, the SIM7000 module is no longer able to communicate sensibly.

When powering on the shield, while listening for any incoming data over serial, I get unintelligible data like this:

�

What could be the cause? I've set the baud rate to 115200 (as it was before when it worked), and also tried the baud rate synchronization walz (AT until OK).

I did manage to get a reasonably sensible output once, when it just sent \x00 (null). That was promising, but also the only thing it said.

No External MCU Needed?

SIMcom released a media statement [1] earlier this year about the SIM7000G, and it suggests that no external MCU is needed:

4. Supports secondary development and saves costs: Without the need for an external MCU and by fully using the resources of SIM800/SIM900 wireless modules, it enables function to port and embeds programs that otherwise would have been implemented by the external MCU into the wireless module, achieving savings in costs. Moreover, RTOS multithreading, messages and other technologies are used for more efficient development. API interfaces of hardware are used for reduced difficulties in development.

It looks like you use an Arduino in all of your examples, but have you been able to use the shield standalone, or is the shield configuration limiting that feature of the SIM7000?

3g/4g link with ESP32 for quad-copter

hi , sorry to open ticket for my question but actually I've intend to use 3g/4g link along side with my Ardupilot compatible hardware which is based on ESP32, but I don't know which SIM series suitable for this matter whereas any drone can fly above the telephone towers and hens communication quality may drop down , also co-working different radio frequencies (3g/4g, wifi, telemetry) would be an issue for itself , so I really appreciated to have your advises for this matter

esp8266 package 2.4.x?

In the examples I read:

Go to boards manager and make sure you have 2.3.0 of esp8266 package! 2.4.0+ won't compile

But what is the issue and why doesn't it compile?
I have several projects for my esp8266 modules with the 2.4.x version, so I would rather not create a fully separated environment just to use 2.3.0.

Also, are there any constrains on the version of the arduino ide then?

Confused: Can SIM7000 MQTT via NB-IoT

Hi,

I'd like to transmit GPS location to server.
The requirements is to transmit using "NB-IoT"

This example seems to use MQTT and allows the option to use NB-IoT/Cat-M module
https://github.com/botletics/SIM7000-LTE-Shield/blob/master/Code/examples/IoT_Example/IoT_Example.ino#L105

Is it true that all I need is an NB-IoT enabled SIM card and network
It will then automatically publish to my MQTT Broker somehow?

This module seems to support 2G all the way to LTE, supporting MQTT, FTP & HTTP
How do I know if NB-IoT is really being used?

Thanks!!

B05 Firmware

Has there been a formal release of B05 as yet?

I noticed that Telstra (Australia) have recently issued an approval for the 7000E module for firmware rev. B05. Approval issued 28 May 2018.

Reference: http://simcomm2m.com/UploadFile/TechnicalFile/SIM7000E_Telstra_Certificate_2018.PDF (may require a login?)

Also worth noting that a Telstra approval is good news for shields sold in Australia.

APN Settings for Telstra:

fona.setGPRSNetworkSettings(F("telstra.internet")); // For Telstra (AU) SIM card - CAT-M1 (Band 28)

Generic MQTT

Hi,
This might be pretty lame to ask, but how do I use your sample code with my existing own MQTT server and not with Adafruit or CloudMQTT as described in the examples?

QMI

Hello!

Thank you for sharing your valuable insight on this new, rather new chip! I am looking to use this SIM7000(E) as a modem on my OpenWRT router. I bought the chip on a mPCIE board, and its listed with PPP capability. But when installed, it lists a QMI dev, but I can not get it to work. I can not find the promised "Linux" driver for this chip either. So my question is: Do you know if the SIM7000 supports a QMI modem interface (with time, and kernel support), or is this some common simmcom interface, and not supported? Can not find proper documentation any place.. Thanks if you have any info to share. I`m also new to PPP, so I would be happy if anyone know of a working chatscript for SIM7000 and using CAT-M1.

Thanks,
Best regards

Linux hangs

I noticed that new Linux kernels (> 4.x I believe), already have SIM drivers in option.c.
Did you test it?
It apparently works, but sometimes the whole systems hangs and must be rebooted.

getNetworkStatus uses +CREG, should be +CGREG

When using the SIM7000E with an NB-IoT-only SIM (no GPRS support), CREG never returns the correct status, only 0,0 or 0,2.
CGREG however works as intended. Could this be changed in getNetworkStatus?

Linux USB Driver

I am trying to support Raspberry Pi 3. The linux driver code has the 7100 but not the 7000 listed.
When I try to compile on raspberry - jesse it gives error:

The Simcom site says there are both linux and android drivers for the 7000, but I can not find them.

The module works perfectly with Arduino! Thanks.

Add the incoming call example

Hi add the calling features in your example
I had seen in adafruit fona lab there is a example on incoming call.
I need to send the GPS value through SMS when someone miss call me .
That is when the incoming call arrive than tack the phone number and send the SMS on that no. With the GPS coordinates.

Support

Hi,
Thanks for sharing the work.

Will this library also support other modules like SIM7100, SIM750, SIM7600?

Program memory requires more please reduce

Sir good evening
I run the IoT example everything is great but the Arduino Uno r3 has 32kb of ROM and 2kb of RAM and the IoT example requires 80% of ROM and 81% of RAM so that I get a problem because I want to embade the impact sensor to detect the accident but because of memory I can't embade
Please reduce down the memory requirement by that I can connect extra sensor and improve my project
Sir if it possible than try please thanks
