Yes, during sleep the BLE is completely off. It advertizes / broadcast its data for half a second every minute. My node is running on a 500 mAh LiFePO4 battery...

Thank You for Your reply! I have forked the repository and added the variants.h/cpp files for the board. I extended the boards.txt too. In the Arduino IDE I can select...

It looks rather promising now. I have managed to build a new bootloader with Softdevice 140 7.0.1 and flashed it to the MDK Dongle. The example sketch "ot-udp-echo" builds and...

While the radio and serial works, it is not possible to use the digital io pins. A blink sketch compiles and uploads fine, but the LED stays dark (while the...

I'm completely lost. I have flashed CircuitPython on the board (officially supported) with Softdevice 140 6.1.1 and everything works - LED's, I2C, DigitalIO. I looked at the pin definitions in...

@soburi You made my day! That was exactly the problem. I changed the number of pins to 25 in the variants.h and enumerated the pins 0..24 in variants.cpp. Now the...

@soburi I have tested successfully I2C and SPI peripherals. Everything looks good, so I've made a pull request. Thank You very much for Your support!

Hello soburi, when using CircuitPython the board enumerates with vid 0x239A and pid 0x80DD, so I've used that. I have also fixed the analog pin definition. _This PR is useful...

Hi, as far as I know, the ESP32-S2 chip doesn't have bluetooth capabilities. [https://www.adafruit.com/product/4653](https://www.adafruit.com/product/4653)
