Revision:
58:113d2ef978d2
Parent:
55:00c1f5b83920
Child:
59:38e56c85fa44
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.
