I have a Telit GL865 GSM/GPRS module which is connected to a SBC (running ARCH Linux.) via Serial Port. For GPRS connection, PPP connection as indicaten on this page.
I want to read Cell Tower Signal Strength by the following AT Command: AT+CSQ?
But I can not use AT commands (AT+CSQ?) if PPP connection is active. First I detach/release PPP connection. Than I can use AT commands. Reconnection to the GPRS tooks about 2-3 minutes. But I do not want to wait for this delay.
Is there any way to check Cell Signal Strength Level or running this AT command (AT+CSQ?) without closing/disconnecting the PPP Connection?
