Hi Quentin,

In general, what you try to do should be possible. However, we do not have any sample which demonstrates how this (large downloads using MQTT) can be done. In addition, you should consider memory requirements for wi-fi supplicant. There might not be sufficient RAM on nrf52840 for wi-fi supplicant. You can look at software maturity levels for wi-fi features.

Best regards,
Dejan

Hi,

I'm planning to use an nRF70 series which would implement the MQTT then a nRF52 series which samples a sensor.

The objective is to update the code of the entire sensor network just by sending the .bit on an MQTT topic.

The main application will be on the nRF52 to sample sensors and communicate with the nRF70 to return the data

Thank you for your help,

Quentin

Hi Quentin,

Which NCS version do you use?

[quote user=""]The last thing I tried was flashing with MCUBoot and Sysbuild through UART and BLE and I've seen some boards were capable of FOTA over WiFi and over external flash.[/quote]

Which board do you plan to use?

Can you provide more information about intended setup?

Which application do you consider running on your board?

Best regards,
Dejan
