I am trying to transmit header with raw data from master side to slave side. Header is successfully transmit from master side but in receiver side we can't receive that header because receiver gone in idle mode. how to avoid or reset that in receiver side.
The IDLE is default active state of the internal state machine. After module leaves INIT mode it goes to IDLE and in case of Slave it waits for header. If the header is not received you must have some wrong module/pin configuration or wrong wire connection.
