Hi all, I'm doing a bit of work with Ofono again, extending support for a Quectel EG91 - handling additional cell strength information which seems necessary for LTE. I'm using Quectel's AT+QCOPS which is returning some negative signal strengths and after some investigation I've spotted that gatresult::g_at_result_iter_next_number() doesn't handle negative numbers. No doubt there's a better solution than mine, but this does appear to work.
