Other Parts Discussed in Thread: SYSCONFIG
Tool/software:
I am testing transmission of 1 Mbps proprietory mode with cc1314R10. In CCS there is no option for 1 Mbps, so I have modified the 500 kbit phy with the parameters from the 1 mbps phy that is present for the CC1312.
This does not work, I have some test data here, setup is a LP-EM-CC1314 that transmits Ethernet packets over radio, and received on a PC with SmartRF Studio and a LaunchPad CC1312 as receiver.
This setup works perfectly if the transmitter is a self designed board with a CC1312. To eliminate board issues I am using a Launchpad and SmartRF studio as receiver. Here is a dump of packets received:

What can be seen is that all packets start with byte 3 of the ACTUAL packet, it contains a one byte ptype indicator, followed by the data. These three captured packets start with 4 bytes 0xff, these are actually 6, so two are lost, as well as the preceeding ptype byte. Also this proves that we are on frequency, with correct bitrate since part of the data seems reasonable. All packets have a CRC error, where there can be many explanations.
Thús, the identical code that communicates perfectly cc1312 - cc1312 does not receive cc1314 transmissions to a CC1312.
All I want for Christmas is an 1 Mbps entry in CCS that creates a good working configuration for CC1314 that is compatible with the CC1312 implementation.
Regards and I wish you a happy holiday,
