From 2ad33244db816755a27dcdd312a70d966c85f0ee Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Thu, 30 Apr 2015 17:44:59 +0200 Subject: [PATCH] at86rf230: move cal_timeout to state change This patch moves the calculation timeout of TRX_OFF to RX_AACK_ON handling to the async state change functionality. With this patch we can do a reset of calculation timeout when others TRX_OFF to RX_AACK_ON happens instead of doing this on interface up only.
