nrf9160 SLM DFU AT commands (#XDFUGET)

[yesheng]

Hi,

I'm interested in using this AT command to upgrade my nRF52840. But I'm not quite sure what to do exactly. I'm using nRF5 V17 SDK on nRF52840. what should I provide for image_1 and image_2 if I only want to upgrade the application only? (not softdevice, bootloader). Also, I would guess I need the UART DFU enabled on my 52840. Is that correct?

Thanks,

Hi Ye-Sheng, 

According to this case:  Socket recv returning -122 (nrf9160) 

There is a limitation of TLS that the max limit of response size of 2kB. When none TLS can have longer size. 
It might be related to what you found that HTTP work but HTTPS (secured with TLS) doesn't work ? 
I'm not so familiar with the SLM DFU, but is there any way you can change this response size ?
