Hi at all! I have a Arduino Atmega328 nano, with a HM 10 Module. The POW leds is on, also the led on the ble module is on, but when I press the reset button, the L led blinks once for a fraction of a second, and then nothing happens. I cannot even send AT commands... any commands I send to the bootloader, the arduino does not respond. Why? The last thing I done is changing the baud rate... Why???
any commands I send to the bootloader
How are you sending commands to the bootloader?
I send commands via BLE, wth the hm 10 module connected on the rx-tx pins
