From 4d7101d76572257dbbdca0e17f132a04e4b2b77d Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Tue, 6 Sep 2016 09:50:04 +0200 Subject: at86rf230: fix cca ed values for rf233 This patch changes the rssi base value to -94 for at86rf33 transceivers. The code before assumes a rssi base value of -91 which is for the at86rf231 transceiver only. This change need to update the cca ed threshold mapping table.
