Make sure you use the same sync word for both devices. CC1101 typically uses 0xD391 D391, whereas the CC1310 SW examples uses 0x930B 51DE. Change CC1310 sync word to 0xD391 D391.
Also, can you get the more simple example such as packetRX and packetTX to work?
Is there a way to send 500mseg of preamble on the CC1101?
Hi Alejandro
The CC1101 works in the way that if you send a STX strobe without having written any data to the TX FIFO , the radio will start sending preamble, and it will do so until there are data in the FIFO to be sent. To communicate with the CC1310 running rfWakeOnRadioRX example you can simply strobe STX, wait 500 ms and then write your packet to the TXFIFO. The only thing you must make sure in such a use case is that you fill up the FIFO over SPI faster than the CC1101 transmits the data, to avoid underflow of the FIFO.
