I’ve received a couple of ProS3 devices. The run the LED lighting code fine but that is not what I bought them for.
I’m using Linux Mint 64 bit and Thonny 4.02. I’ve been able to install pros3-20220618-v1.19.1.bin but when I go to the main interface and click the “Stop” button (even after reconnecting the Esp32) I just get:
I’m not sure exactly what’s caused that issue but I’ve found a few similar reports that were caused by having the ESP32 variant set slightly wrong, which caused the chip to fail to flash correctly. If your standard blinky sketch works ok but the other binary doesn’t is it possible it was generated for a slightly different ESP32 version?
Other users have got similar error messages related to flash either being present or not targeted correctly for their specific board variant.
In the future I’ll use esptool.py directly for flashing. Thonny uses esptools.py but clearly doesn’t pass the correct starting memory address for writing.
I bought 2 ProS3 boards and left the second alone. It is probably good to use as is but both boards booted up and run a RGB LED program and don’t have boot.py or main.py. I prefer to build on a solid platform.
I had no problems getting MQTT running so don’t expect problems when I get serious.
Thanks again Liam.
