Issue in basic TX & RX path with MKW01

Discussion created by Saurabh Jhamb on May 26, 2017

I am trying to establish basic TX and RX communication between MRB-KW019030JA and USB-KW019032.

USB-KW019032 config:
- RX Mode
- Configured to RX at 865 Mhz and 4800bps
- Fixed Packet Length - 5
- Sync word of 2 bytes - 0x90,4E
MRB-KW019030JA config:
- TX Mode (keeps sending 1 packet of 5 byte payload every second)
- Configured to TX at 865 Mhz and 4800bps
- Fixed Packet Length - 5
- Sync word of 2 bytes - 0x90,4E

(Attached spectrum analyzer snapshot of RF transmit @ 865Mhz)

 

TX is issuing with PacketSent Interrupt, hence seems right.
RX is responding with RXReady so ready to receive And even sets Rssi bit, but doesn't receive anythign (sync match bit is not setting).

 

If I lower threshold, RX receives noise and issues Sync match (only if TX board is OFF). If I turn ON the TX board nothing is received.

 

Kindly help!
