sx1276/sx1276-arduino-hal.cpp@58:113d2ef978d2, 2017-05-25 (annotated)

Committer:
Helmut Tschemernjak
Date:
Thu May 25 21:56:39 2017 +0200
Revision:
58:113d2ef978d2
Parent:
53:6d3adad59633
Child:
61:08b50780eb91
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.
