ESP32 with TFT display as small weather station displaying local and internet weather data

ESP32 Weatherstation

ESP32 based Weatherstation Uses attached sensors, remote sensors and Internet weather information to display current weather on a 1.44" TFT display.

Detailed informations about it are on my website

Development platform

PlatformIO

Used hardware

• Elecrow ESP32 WIFI BLE BOARD WROOM
• Elecrow 1.44" TFT display
• Adafruit TSL2561 LUMINOSITY/LUX/LIGHT DIGITAL SENSOR BREAKOUT
• Elecrow DHT11 TEMPERATURE AND HUMIDITY SENSOR
• LDR
• 10k and 2.2k resistor
• ESP8266 security module with PIR, light relay, alarm buzzer and DHT11 temperature and humidity sensor (optional, another DIY project)

SW practices used

• Use of ESP32 HW timer
• Use of SPI (for the TFT display)
• Use of I2C (for the TSL2561 light sensor)
• Use of bit-banging 1 wire interface to DHT11
• Use of ESP32 touch interface
• Use of ESP32 multi tasking
• Use of ArduinoOTA for SW updates
• Use of MQTT for web based information display
• Use of UDP broadcast messaging
• Use of UDP broadcast receiving
• Use of TCP socket server to receive commands
• Use of BLE for sending sensor data
• Use of Bluetooth Serial for debugging

esp32-weatherstation's Issues

Time sync via BLE

ESP32 Bluetooth Serial for iOS

Hi, I came across your website when looking up how to use iOS with ESP32. I want to use the BluetoothSerial to have a way to connect to UART devices with my iPhone but it doesn't work. I saw you mentioned using BLE with BluetoothSerial, have you got a working example? I saw some code on https://github.com/beegee-tokyo/ESP32-Weatherstation/blob/master/src/ble_bt.cpp but am lost.

I just am trying to use my iPhone with my electronics modules. Could you please help?

Bluetooth SPP + BLE Server

I followed the reasoning in https://desire.giesecke.tk/index.php/2018/02/27/esp32-bluetooth-serial-and-ble-server-running-together/ just this evening and I tried connecting to the ESP32 using the nRF UART Android app as well as the Serial Bluetooth Terminal Android app. It failed with in both cases with similar messages indicating that no Serial Profile was found. Have you tried this recently (i.e. with the 1.0.4 Boards Manager release of arduino-esp32?
