Question
S2LP StatusByte 0x52 0xE9 error
Hi, I try to transmit data by S2LP(RC-S2LP-433) and have a problem. When I try to debug the unit (true studio) everything work great, when the TX end then get an ISR to reset flag and in main loop start new transmitt. When I try to start the unit without debugging mode, only give 3V to the my board then don't transmitting and give an status byte[0]=0x52,[1]=0xE9. The S2LP chip is version 0x91. Can anyone help me?
