Ok. I don't know if there is a way to execute a pin higher priority interrupt than Bluetooth communication?

I mean that a rising, falling, change ... etc. in a pin cause an interrupt no matter what a bluetooth event is triggered?

In that case, there is little you can do with this code; your code effectively assumes that the core is 100% under your disposal at all times, while in practice BT sometimes needs to respond to things and steals some time. You may be better off doing things in hardware: either see if you can put th...

Moving to the Arduino subforum Bluetooth will eat up some of the processing time of the ESP32 and can indeed cause latency issues, although iirc Arduino runs BT on another core than the user program task. Does your code still have timing issues when you comment out the SerialBT.println line? It mig...

Hello everyone I am trying to make a code to control the intensity of incandescent lamp (AC voltage). I use a signal zero cross circuit to synchronize the signal control of the ac load. The value of the intensity is given by a bluetooth device (android). The initial intensity is 50%. My code is the ...
