Hi, i have build it today, so far its working but didn't shows the right Information on oled instead it shows garbage.
Its an 128x64 oled.

Mistakenly I connected the battery when USB cabel was attached.
It fried the regulator on the ESP32

Hi!

I was wondering if you can share a link to the board that you're using to built this.

TY.

please resubmit the app

Hello, I am getting the following error when trying to compile the project:

C:\Users\AlphaFPV\Documents\Arduino\libraries\ESP8266_and_ESP32_OLED_driver_for_SSD1306_displays\src/SH1106Brzo.h:35:22: fatal error: brzo_i2c.h: No such file or directory

The libraries have been correctly installed, and the error happens both with the .zip lib or with the downloaded one.

I try to upload the laptimer code, but arduino ide - gives the following error message:

ESP32LapTimer:7:21: error: ESPmDNS.h: No such file or directory

compilation terminated.

exit status 1
ESPmDNS.h: No such file or directory

Thanks for your help

Makes sense we should have this and will be useful those of us that bury our boards in a case.

Pulls could also be accompanied with a .bin for easy uploading and testing.

We are currently only using a threshold based approach, where we trigger a new lap as soon as the threshold is reached. I think I don't have to explain, why this isn't ideal.
I did some test with a simple max based approach, which showed a significant difference in time (about 50ms): https://github.com/Smeat/Chorus32-ESP32LapTimer/wiki/Data

The original project also has another trigger mode which might be worth a look

Hi!

I've been trying to use the chorus RF laptimer App as listed on the README, and I can't see any of the info in the app.

I connect my android device to the Chorus32 network and signed into the network. I can see and change the setup. If I go to the Chorus RF Laptimer app, I can connect to the network (and it toast a "connected to 192.168.4.1". But there is nothing at all on the Freq and Pilots tabs.

On Race there is two buttons "calibrate timers" and "start race", which are disabled.

I've seen that in comms.ino there is a lot of functions related to chorus API, so that make me think that it's already implemented, but I'm not sure if I'm missing something.

Thanks.

Build in VScode with platformio extension. In Buttons.cpp change:
from
#ifdef USE_NORMAL_BUTTONS
to
#ifndef USE_NORMAL_BUTTONS

Another, got issue #127

If the software could set all 6 modules, to the same Rx frequency and select the strongest output, via a video switch f.i. 2x CD4066, the unit could be also used as a long range multi diversity basestation with several hi gain antenna.

As here:

Use with LiveTime requires serial correct?

Hi!

I was trying to use this project and I'm not being able to connect to the wifi configurator.

I've flashed the code with no issues. Also flashed href="https://github.com/me-no-dev/arduino-esp32fs-plugin pluging and uploaded esp32 sketch data.

I can connect to wifi AP, but android doesn't ask me to sign in the network. I've looked into the code, and the wifi AP seems to be 192.168.1.4, so I've tried to log using chrome, not luck again.

Here is my serial monitor output.

Hi! I just noticed the iOS app was no longer available.

Hey Guys,
thanks for your project but i have one issue.
because i cant connect with the app over wifi, i activated bluetooth.
This works ok with the App but if i want to change something in the WIFI settings Page,
the Module reboot directly after i connect to the wifi Network, closed the wifi,start it again and dont show the page.
do you know something about this issue?

BR Peschi :)

For full LiveTime compatibility, a call to Chorus to get the time must be on the same clock as time reported for lap crossings.
This would require a new Race mode.

Requested addition:

3 = Race mode 3: lap times are relative to the time value in milliseconds from Arduino startup, in sync with the time send when making the 'r' call

Can I just hook up an RX5808 to a ESP32 and run this project or do I need the PCB including all the other components?

By the way if there's a better place to ask questions like these please let me know!

I was thinking about a json rest api to communicate to and from apps.

Could be really easy to create and android app that allows to configurate the project instead of using a webserver.

The app also could be used to visualise lap times.

I have already started digging into how to create the json parser in the esp32, and got plenty of experience in software developing.

Will be nice if you can point out what needs to be changed with the app. I'm thinking about:

Timer active
Frecuency of video
Vbat scale

Hi!

I was thinking that it would be nice to have a chat (telegram or slack will be nice) in where the people who are developing the project could chat about it. I think it will decrease dev time.

I'm going to be coding a lot for the project and would love to have a chat room to discuss some stuff.

@AlessandroAU Please, let me know what do you think about it.

Move Platformio.ini and .gitignore out of ESP32LapTimer folder

Hi!

I started to create the interface for updating band and channel from webserver:

The select items are showing bands and channels and will be showed with the parsed value from the configuration data.NumRXs. So, ie: if data.NumRXs = 4, only 4 VRX configuration will be showed.

Channels can be chossed from 1 to 8 and bands ussing their "names":

As I click the update button on index, the url will be:

updateGeneral?NumRXs=7&band1=R&channel1=1&band2=R&channel2=2&band3=R&channel3=3&band4=R&channel4=4&band5=R&channel5=5&band6=R&channel6=6

Where each band and channel are sended ussing the same pattern.

I assume data transfer is going to be recieved at this line in webserver.ino

And needed to be stored in the eepromsettings. I think they need to be stored in RXBand, RXChannel and RXFrequencies.

I don't have the project with me, so I can't test it out. but will do during this week and let you know.

If you got any suggestions, please, feel free to contact me.

The ESP32LapTimer.ino file says to check the readme but the information there is quite sparse :)

UPDATE: Here is how I did it.

• Pull Chorus32 from github
• Install Atom
• Install Platformio
• Import Arduino project in Platformio
• Specify the upload port in platformio.ini (eg. upload_port = /dev/cu.Repleo-CP2102-0001)
• Start Platformio Terminal (shift+command+T)
• Run pio run -e BOARD_OLD -t upload
• Hold boot button (important on my board!)
• Run pio run -e BOARD_OLD -t uploadfs
• Hold boot button
• Connect to Chorus32 LapTimer wifi
• Open http://192.168.4.1/
• You should now see the configuration page

Use BOARD_OLD if you are using this wiring schema and BOARD_DEFAULT if you're using the PCB v2.2 wiring schema.

Hi!

How do you modify channels assigned to each ADC?

Seems like we have some beeper code, but it isn't really used anywhere.

A solution would require the use of "vTaskDelay" or a similar approach, which doesn't use a busy wait (aka "delay") as well as the implementation of the "sound" message to disable/enable the sound.

Hi

I want to use an OLED board for this Project.
So can you provide Connection diagram for connecting ESP32 and RX5808 module

Sorry I don't know how to contact you for further Info about this Project.
Waiting for your reply

Thanks in Advance
SHIRISH

I'm building a setup based on this wiring schema.

Does this schema match the BOARD_DEFAULT or the BOARD_OLD build target?

The reading from my INA219 off by about 0.3v compared to when I read voltage with a multimeter across the battery + and -.

I've got the VIN- connected to + terminal of the battery according to this schema.

Did a miss a wire or setting somewhere?

Does anyone have succesfully connect chorus32 to fpv trackside?
There is chorus32, but I have no luck to make it work.
With android chorus app it works well

I've noticed that the ADC4 value on my new build is spiking around a bit. With nothing transmitting, RX 1-3 report RSSI bouncing between ~78-83ish, fluctuating by 5 or so.

RX4 reports RSSI bouncing from 78 up to 110 or more at times, briefly, and then back down. I've also noticed the OLED will show that bar fill completely (like, off the chart) for a brief moment and then settle down--although in-app RSSI monitoring does not show those massive spikes.

After seeing similar interference from the jumper pads under the OLED, I'm wondering if it has something to do with a voltage rail near the ADC4 trace or something, since my point-to-point build does not exhibit this behavior. Especially since RX4 is powered from a different power rail than RX 1-3 are (the upper buck converter vs the lower one).

I will be double checking all my solder joints, and also try a different ESP32 (I bought a 3 pack, and socketed the ESP32 into the board for easy swapping), but was wondering if anyone else has seen similar behavior. Perhaps a different type of filtering or something?

Hi, is this still in Developing?
I Have no Speaking on IOS, iPhone 14 up to date.

Both TBS and Immersions personal tracker offerings both use one module. I think this is worth perusing even loss of resolution. Might not be a good solution for large races, but practice days 1-4 pilots or even tinywhoop might be a good idea.
According to Immersions laprf app:
1 Pilot - 30ms/160kmh
2 - 60/90
3- 90/75
4-120/50

Plus battery life will be better, lower price, reduced BOM count, and smaller form factor.

Would be possible to implement a mode in which esp32 makes the vrx jumps through channels really quick?

That way it would be possible to reduce the number of vrx to complete the project.

I have found this on Youtube and was wondering if it was possible to integrate this in Chorus32?

We've never specified a license.
We are also required to attribute the original project (if we have any original code left).

Personally I'd prefer a license with copyleft (like the GPL), but would also be fine with the MIT license like the original project.

Whatever we choose, we need permission from all contributors.

Thoughts? @JyeSmith @AlessandroAU @LuisDiazUgena @mike-levenick @swampmonster

A calibration setup is going to be needed to optimise the Rx multiplexing feature. This is the same as what Fatshark modules do e.g. checkout https://github.com/sheaivey/rx5808-pro-diversity and how it normalised a max and min RSSI.

Multiplexing a single Rx to multiple frequencies will work as is using the Rx raw RSSI and current threshold method. But let's say you have 6 Rx modules and want to run 8 quads?

You could use all 6 Rx modules to measure quads 1-6 RSSI, and then use Rx 1-2 to measure quad 7-8. This will also work with current raw RSSI readings and threshold. But you now have 60ms between every quad RSSI measurement.

Or we can use Rx 1-6 to measure quad 1-6, then Rx 1-6 for quad 7,8,1,2,3,4, then Rx 1-6 for quad 5,6,7,8,1,2, etc. See how this drops the measurements time for each quad to 30ms with an occasional 60ms gap.

The problem being that quads will be measured using different Rx modules, so an RSSI calibration is needed.

How? Add a start Calibration button to the web server. With a quad set to 25mW 1m from the laptimer the Rx modules will sweep the frequency table looking for high and low values. These are used to map the raw RSSI readings.

I can’t locate the lap timer on my iOS device(iPhone 6S Plus and IPad Pro).

Does not show up in Bluetooth at all, and when I try connect via WiFi it crashes the app or I get an API version error (node(1 has API version: 4 and node(0 has API version: 4)

Am I doing something wrong? I do see it on my MacBook under Bluetooth but not on any mobile devices.
