Hello people, im making a simple fixed wing controller. Basically, everything works perfectly until i enable power amplifier. My setup is, transmitter: Uno, SSD1306, 2 joysticks, 1 potentiometer, E01-ML01DP5 Ebyte (nRF24L01P + PA + LNA) with standard nrf adapter. Reciever (drone): Mega2560, 2 9g servos), also E01-ML01DP5 Ebyte (nRF24L01P + PA + LNA), 30A esc and motor. However i dont think receiver is problem here. When radio modules are set to "radio.setPALevel(RF24_PA_HIGH)" theres no communication. However if i disconnect transmitter and reconnect it, then once again upload the code it start working. I used to run transmitter on power bank (5v 1A) however as i imagine its not enough. It doesnt run unless i do the disconnect reconnect upload sequence. Should i use external power input for radio module? Also unplugging screen doesnt change anything.
