AT^SMONP returns empty response at times | Thales IoT Developer Community

August 28, 2017 - 4:09pm, 1995 views

We're using the AT^SMONP command for cell triangulation. What we regularly see (not only during startup of the BGS5 but also at runtime) is that we get a response

at^smonp

2G:

----,--,----,---,---,-,-,--,--,----,----

The documentation states that

During a CS connection or in Airplane **** the response is empty and displayed as follows:

"----,--,----,---,---,-,-,--,--,----,----"

It is unclear to us when the BGS5 gives that response (what is the definition of a CS connection) or what to wait for when that response is received (what precondition must exist to make the AT^SMONP succesfull).

Could some-one enlighten us?
