I’ve checked out master from the EmonESP repo, and using VSCode with PlatformIO to build/upload. It’s compiling, uploading (both code and SPIFFS) without an issue. I’m using the default project tasks in VSC. I always do an erase before uploading. After a successful upload, the AP appears on my phone, but it’s very hard to connect to it, it has a pretty flaky AP. When it succeeds, it almost instantly drops the connection. I’ve also tried flashing a Tasmota .bin that used to run on this device previously. It works without a hitch on first try, so my setup an the device is working just fine. The device is a generis ESP12S NodeMCU clone with 4 MB flash. I also tried to flash the code and the spiffs using esptool.py directly, to the same effect, sadly.
Am I missing something? Could please someone guide on how to debug further?
