after a bit of searching, i found that the problem come from the line if(pRemoteCharacteristicNotify->canNotify()) still dunno how to fix it, tried replacing it with if(true) to test the next line pRemoteCharacteristicNotify->registerForNotify(ESP_notify_callback); and i still got an error, but this time it was

still no clues at how to fix it

I looked into this before and found the problem was in the BLEDiscoverServices() code. Either way, it's in the ESP32 support and I can't see an easy way to work around it.

DieterKoblenz commented 2 years ago

Sorry, but I had this on two ESP32 models. It used to work on an ESP 32...

@yapudjus did you ever find a way to get it working?

@bitbank2 is there a supported model on which it works?

never made it work, I'll buy an esp8266 and try something else

bitbank2 commented 2 years ago

I'm able to use the printer with the Arduino Nano 33 BLE and other nRF52 devices.

esp8266

An esp8266 doesn't have BLE though, so that's a pity.

Shame that esp32 crashes. I can't remember how I got it working earlier. It's really nice since it has wifi too. The telegram bot is the reason I wanted to use it. But I guess I'm better of with a cheap wired thermal printer and a esp32.
