I am using a sara n211 and want to query the current time using AT+CCLK?.
Unfortunately the answer only consists of an “Ok”.
Does NBIoT support this function?
Dear Sir or Madam,
I am working with your library for NB-IoT. If I understand it right, the library should connect the module (I am using Quectel BC95-G) to the Cloud of Things but I haven’t found a way to include PIN for the SIM card and the communication always stops on that problem. The recorded communication:
Security B… Verified
Protocol A… Verified
Apps A… Verified
Is there anything I am forgetting to implement which will do it or am I missing some part of the library?
Thank you for your replay and have a nice day.
I’m using a BC95 Modem from uBlox. The SIM cards did not use the T-Cloud, instead I want to send and receive packets to our own UDP gateway in very raw format (no CDP or other stuff around).
The sending of packets from the modem to the gateway (listening on port 8472) works fine:
Received from xx.yy.zz.ww, Port 29541: Hello World!
I told the modem to listen at port 8472:
The registration seems to be ok. But sending back a UDP packet to the nbiot modem at xx.yy.zz.ww:8472 did not work.
The packet never arrives. From were did the NAT gateway ‘knows’, at which port the device is listening to?
