I have 2 ble nanos, i upload the same sketch on both (arduinoBLE, LED) and i can connect via nrf connect, and i get the MAC adress on the serial monitor.
But when i try to send "1" to one of the nanos the led turns on and i get the "LED ON" on serial monitor. I turn off that nano and do exactly the same with the second, but it seems that is not recieving anything, but i still get the MAC adress, and confirmation of connection.
tried with different sketches and cant recieve nothing. Is something wrong with one of my boards? Or how can i fix this?
Hope some can help, thanks
All 5 components are present on the pcb antenna
