@rvweert Looking at the logs, there is no bootloader involved (@Oitzu already confirmed this).
This looks like a bad nRF chip and/or power issues (try with different a cap) since the msgs sent from the GW never reach the node.
@rvweert MY_OTA_FIRMWARE_FEATURE enabled in MyConfig.h? This seems to be the cause of the restarting nodes. Try disabling this option unless you are using the sensebender board...
