Getting Signal Strength

[awneil]

@awneil

Note that AT+CCED can be used to request an unsolicited +CSQ whenever the signal level changes

Correction: you get an unsolicited +CSQ whenever the signal level changes except when it changes to 99 (ie, unknown or unavailable).

See: AT+CCED bug?

So, if your application needs to know that, you’ll have to think again!
