CC1120 in OOK no TX

Other Parts Discussed in Thread: CC1120

Hi,

I have CC1120 with SmartRF studio 7 V.2.1 configuation (Bit rate 4.8 kbps, OOK, RX 66 kHz, 868):

// Rf settings for CC1120

RF_SETTINGS code rfSettings = {

};

but when I set STX command, CC1120 still stay in RX.

Why is this happening?

Regards.

Thanks!
