Good morning,
I am working with a BG77 modem and need to know how long the modem remains available for uplinks/downlinks after sending or receiving a message to/from a server.
In my research, I found the command “AT+QCSCON?” which can be used to display each of these changes via URCs. The problem is that I cannot obtain these state changes from the modem automatically. I can get these times manually by repeatedly executing the command, but it is inaccurate.
The commands I have been using are:
- AT+QCSCON=1
- AT+QINDCFG=“all”,1,0
- AT+QINDCFG=“csq”,1,0
An example of what I do before running these tests:

Note 1: Recently, I have been working with CoAP and MQTT, obtaining the same result with both.
Note 2: The current firmware is BG77LAR02A04_01.204.01.204
