Since the company Next Thing Co is in bakruptcy it is harder to find something for your C.H.I.P or your Pocket C.H.I.P. It`s still possible, like on reddit: r/ChipCommunity
So for this particular Problem i found this thread. So you just need to download the file config.json and upload it to your Pocket C.H.I.P in the .pocket-home folder via ftp.
If u need all the “lost” infos of NTC u can download all from this archiv.
