Combining MQTT over wifi with OTA BLE

[saiff]

Hi, i wanted to add OTA DFU to an MQTT application i coded using zephyr APIs on my nrf52840DK with nrf7002ek. 

The problem is that MQTT takes already a lot of RAM and flash memory that eventually there's no more room for BLE functionalities, is there a way to have a "lighter" MQTT application, or is it just impossible to have them both?

Thanks in advance,

Kind regrards,

Hello,

Could you paste the whole log here? Use the insert tab to do that. It's easier to go through the logs than a screenshot.

Kind Regards,
