Thanks to @TonySmith’s post mentioned above, I was able to get rid of the first error:
./reset_lgw.sh: 24: echo: echo: I/O error
The trick was removing power enable-lines from reset_lgw.sh did, which Tony mentioned in his post. One error is remaining, however:
ERROR: Failed to stop TX trigger
Any information about this error would be appreciated. Is it safe to disregard, or will it affect the gateway performance?
Kind regards,
Ketil
