Hello all,
I need to do continuous carrier 4GMSK transmission for a spectral mask measurement. Right now the carrier turns off after each packet even though I have TXOFF_MODE = 10 (stay in TX). How do I configure that the carrier remains on while a packet repeats continuously?
The code does a burst write then strobes and repeats.
Thanks
