Pytrack + Lopy4 TTNMAPPER node

Hi,

as my first hardware node still is struggeling to receive Thethingsnetwork signals after a first hour of working i received a new option to connect to the thingsnetwerk.

i was thinking to start with this node to map and visually log the data.
however all example codes for this device use ABP to connect. after creating the application for this i tried to add a new device, when editing the connection method from OTAA to ABP Saving is rejected: a colored popup: “could not save device settings: Method Not Allowed”

anyone here who knows what’s going the wrong way? newbie in pycom-land willing to learn.
