I hope you can help me with this issue. I already searched around the forum about this topic, but none worked for me.
I need FOTA update on HL7800 Module.
Here the details of the module I am using (to this firmware version I uploaded through the serial port )
I already added the modem to the portal ( but it does not sync with airvantage):
In order to add the required information I used the commands:
- AT+KGSN=3 ( for the Serial Number)
- AT+CGSN=0 ( for the IMEI )
I tried these commands then after connected an APN
I have a VODAFONE NBIOT SIM card and I connect to a public APN ( as in the picture ). Here follows more details about the status of the modem:
Searching in the AT Commands Interface Guide Rev11, we have this “Two IP sessions are required…”. How to perform this? How do I make sure of it?
I am new to working with modems. Please, it would be really nice if I could have guidance on troubleshooting step by step with a real example without any assumption of what might seem obvious.
ps.: We are able to communicate with our server ( I don’t know if this helps) :
