From ed4a26b0995baf10807ebb3f18fba3db2c6539fc Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Thu, 27 Aug 2015 21:49:18 +0200 Subject: [PATCH] at86rf230: interrupt tx with force trx_off To abort a TX_ARET_BUSY state it's recommended to switch into TRX_OFF state by doing STATE_TRX_FORCE_OFF. This patch will do always a TRX_OFF state change when the transceiver stucks in any state. From TRX_OFF we can switch to the states which are also possible by TX_ON state.
