Is there a command to reboot the device?
Can I power off the device with a command?
Is there a command to get the current state of the cellular connection?
Can I increase the position output frequency?

Does the implementation of TCP and MQTT upload work right now in v1.2.49?
I tried both but don't see any data hitting either my internet accessible MQTT or TCP servers

AT+UPLOADDATA_TYPE=GET,0
AT+UPLOADDATA_PARM=GET,1,hub.umagul.net,12000

AT+UPLOADDATA_TYPE=GET,2,USERNAME,user,PASSWORD,pass,CLIENTID,device1,TOPIC,cellular/data,SUBTOPIC,
AT+UPLOADDATA_PARM=GET,1,hub.umagul.net,1883

Can I see the TX/RX bytes transmitted over cellular for the current session?


I'm looking at the protocol for uploading arbitrary data.  I don't want to have defined fields since the data I may want to upload may change.
I'm thinking about doing base64 encoding of my data to allow it to be artibrary and still compatible with the NMEA format.

Something like:

AT+UPLOADDATA_DATA=SET,1,ID,1234,DATA,eyJ0aWNrZXQiOiJBMTIzIiwiZGVwdGhfbSI6MS4yLCJmaXgiOiJSVEtfRklYRUQifQ==

This would let me specify a message ID and base64 encoded data.  I could send multiple uploads per message ID and recontrust on my server.

I would need a way to get a response from the MQTT server to know if the message was accepted and processed. Can we subscribe to a topic to receive feedback?

What is the longest sentance you can handle?
What is the longest field size you can handle and upload?

Is there a way to get information about the base station through the RTCM/NTRIP data being received?
