Hello, I use a microcontroller to communicate with ESP-WROOM-02D module , I use one pin of the microcontroller to control the EN pin of the module, a reset IC to control the reset pin of the microcontroller and the reset pin of the module (Connect the output pin of the reset ic to the reset pin of the chip and module).
Normally, the output pin of reset ic will be LOW(0V) after a period of time (about 100ms) will become HIGH(3.3V). However sometimes I have a problem that the power is on and the output pin of reset IC is always at LOW, when the separation the reset pin of the module, the output pin of the reset ic becomes HIGH. That mean the reset pin of the module becomes LOW output pin?
Please help me what is happen with the module.
