Rak831 using OpenWrt on WisAp

Hi
2 questions,
1
Has anyone got some pointers on how to change the packet forwarder to the TTN one on openwrt?
2
I keep getting “Failed to start concentrator”. About every 5th attempt does start it and then everything works ok. At the moment I am just testing the system and am using the leads that came with the system to join the MCU board to the Rak board. Could this be the cause? and if so are there any ways around this apart from using a PCB to link the two? I have already tried changing the SPI speed but it made no difference, although I might be changing it in the wrong place.
