I also have troubles with Hilonc V2 /HL6528RD network registration (for GSM).
I have at least a hundred Hilonc V2 in the field. According to my experience, when modem is set once with AT+COPS=0 (default settings). The modem is automatically re registering when it can. No need to reset.
However, on one site, with a Orange business card, I have the following issue:
It has been working like a charm for several month and then, one day, the modem has been unregistered.
Even if the signal is OK, the modem never get reregistered. I also tried to reset the modem several times but it always come back with good signal, operator name BUT unable to register.
Here the logs :
RECV:*PSNTRG: 0,0,“208”,“01”,"","",“Orange F”,0
I’m thinking whether this is an operator problem? Or maybe should I set some operator parameters manually?
Thanks in advance for your feedback
