Preparation

Open a serial terminal and connect to the BG95-M3 module using the AT command interface.

Network Registration

Ensure that the module is registered to the cellular network if not check the recipe BG95-M3 Network registration

Check Signal Quality

+CSQ: , is the received signal strength indication, expressed in dBm. The higher the value, the stronger the signal. is the channel bit error rate, expressed as a percentage. The lower the value, the better the channel quality.

Set the APN

Set the Access Point Name (APN) for the network connection.

Activate the GPRS connection

This command attaches the module to the GPRS network and activates the PDP context

Get IP Address

This command retrieves the IP address assigned to the module by the network operator

ICMP Ping

After the successful setup of the data session, with 'AT+QPING="www.1nce.net"' any URL or IP address can be pinged. The responses '+CIPPING: 0,"15.197.142.173",32,459,255 show the resolved IP address and the ping time.

Wrap Up

This guide showed the basic setup of a BG95 with a 1NCE SIM to get an ICMP Ping request working.
