I guess an AT command was issued that caused it to only have an AT port for a second and then just lose it. The ports show up but are not accessible. This was with the original rm510q GL engineering firmware. He then flashed it to rm500q GL production firmware and the issue is the same. I'll try to source the rm510q firmware. Thank you.
