QT Py ESP32-C3 BLE Flaky Connection

Post by stumpylog »

I recently purchased 2 of the Qt Py ESP32-C3 boards, one of which is to replace a HUZZAH32 in a smaller form factor for listening to a BLE cadence sensor.

When I changed uploaded the same sketch to both boards, they have issues connecting to the sensor and once connected, will often drop/miss notifications from the sensor. This sketch works great with the HUZZAH32 and I took an TinyPico out of a different project, which also had no problem.

So it seems to come down to the ESP32-C3 boards only. I might assume a bad board or something, except both exhibit this. I am using the 2.0.5 release of the espressif/arduino-esp32 library. Are there known issues around BLE on the -C3 boards?

There are some open issues in the github repo espressif/arduino-esp32 for the esp32-c3.

Maybe of more interest is the recent check-ins of more example code for the ESP32-C3.

C3 is very new, would not surprise me that BLE is not as solid as the very-well-used-for-5-years ESP32

I guess I was imagining since it was announced about 2 years ago, it would be fairly stable. But maybe it's more about when it actually started producing and getting put into boards.
