Revision:
58:113d2ef978d2
Parent:

Child:
60:75426c142f6e
Removed duplicate timer definitions (left over from previous cleanup)

zapping the receive buffer makes no sense, keeping the content is better

and allows coping the data while we are receiving the next packet.

The State = RF_IDLE is already done in the sx1276 constructor,

no need to do it in the HAL layer.
