From 2f8cdd95097bdcd8d1e2b02edb0a9deb1e034a7e Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Thu, 30 Apr 2015 17:45:01 +0200 Subject: [PATCH] at86rf230: remove unnecessary tx state change All supported transceivers can do a valid state change from TRX_OFF to AACK_ON. This patch removes the state change chain from TRX_OFF -> TX_ON -> AACK_ON instead we doing a directly state change from TRX_OFF to AACK_ON.
