Dynamic selection of Wifi or LTE on Thingy91X

[JRSN]

Hi all,

I could not find similar questions raised on the forum and I hope someone can help me.

I have an application to connect to a mqtt server, developped on the latest NRF Connect SDK release, 3.0.2.

It works well over wifi on nrf7002DK and over LTE on Thingy91X and nrf9151DK.

Now, I need it to be able to work over Wifi or LTE on Thingy91X depending, dynamically choosing the proper link, on the spot.

I have analyzed the mqtt sample but it does not help finding the solution.

Any hint would be much appreciated.

Hi

As far as I know there is no API available for doing LTE and Wi-Fi switching dynamically as of yet. Falling back to LTE if Wi-Fi isn't available (or vice versa) should be possible during setup, but not dynamically. Can you share some details on your use case where this is necessary and I can create an internal ticket so we can start looking into creating an API for this on our side.

Best regards,

Simon

Hi,

Thanks for thinking about improving the API and sorry to revert back so late.

Thue use case is : a sensor has to send data via MQTT preferably over Wifi, but over LTE when Wifi link is broken ... or vice versa. So it would be perfect if the API allowed the application to be informed of Wifi or LTE link status change to switch to the allowed one.

Tell me if you need more insight ; I would be more than happy to contribute to API additions
