Hi,

I've just got the steval-sp1ml868 and have been trying to gave it communicate with TI transceivers CC1111/CC1101. The TI transceiver works in the same 868 MHz and so far I have been able to receive radio messages from TI transceiver, however when I try and send something out there is always a byte appended to the end of my packets, I would appreciate any help as to how to overcome this.

thank you

Yes I've been following them, by using

http://www.st.com/content/ccc/resource/technical/document/user_manual/1a/d4/96/96/c5/93/4c/f4/DM00178464.pdf/files/DM00178464.pdf/jcr:content/translations/en.DM00178464.pdf

and the datasheet for the Spirit1 I've been able to send and receive packets from the CC1111, however the issue occurs when I send packets out and there is a byte appended at the end of my payload and I'm unsure how to overcome this.
