RAK7268CV2 LTE Modem option/operators

LPWAN Industrial Gateways / Concentrators
1

I’m using some RAK7268CV2 EU version and I selected LTE modem.

Unfortunately I’m coming from Teltonika RUT240 device with great option to select and chose various parameters on LTE such as best signals and operator selection. So I’ve got a bunch of question. Love WISDM interface to manage gateways, but looks likes option about LTE are really limited.

  • When using mutli operator sim card how the gateway (modem) select the operator does it scan best operator?
  • Once connected to one, does it stick with even if changing gateway location?
  • Does it scan on each reboot?
  • Does it choose randomly?
  • Can we scan for operators around?
  • last but not least, how can I set/fix operator needed?

There is absolutely no information about that in documentation, I can do that in command line connected to the gateway, but I can’t find any information on how do to that and even if it’s possible to send modem commands @carlrowan

Thanks

Hi @Charles ,
The cellular part of the gateways is left simple in the WisGateOS2 WebUI.
It is possible for specific settings to be configured from the CLI with AT commands to the cellular modem directly.

  • When using mutli operator sim card how the gateway (modem) select the operator does it scan best operator?

A: It selects the best signal network. Note that usage of APN is important and preferred.

  • Once connected to one, does it stick with even if changing gateway location?

A: Depends on the APN, if provided for specific network it will try the network for which the APN fits. But otherwise will use the best signal.

  • Does it scan on each reboot?

A: Yes

  • Does it choose randomly?

A: No, best signal.

  • Can we scan for operators around?

A: Yes, but only from the CLI interface and with AT commands.

  • last but not least, how can I set/fix operator needed?

A: Yes, it is possible with AT commands from the CLI.

Hi @velev

Thanks for this clarification, crystal clear, we use APN but our APN is able to connect to different operators here in France (Orange, SFR, Bouygues) and only one APN (and same) is used. So I guess if it scan it will use best signal operator.

Anyway do you have any example or documentation on how to use CLI with AT command, I’d be interested to test and know how to do that and have command list we can use

Thanks
