Disable SMP server n seconds after MCU booting

[Pedro]

Hello!

We have an application with an nRF52832 connected through an UART to another MCU. We want to have the possibility to update the nRF FW, but as nrF52832 only has 1 UART, there is no straightforward way to share it with APP and SMP server at the same time.

Is it possible to do the following?

1- Boot with SMP server and wait a few seconds for an incoming image upload command.

2- If no SMP communication is received after n seconds, disable SMP server until next reboot and start APP which can use UART without problems.

Thanks in advance!

Regards.

Hi Sigurd,

Thanks for your answer! I also think Serial Recovery is the best option in this case. 

I do not need dual slot having serial recovery. In fact, the current .bin size is close to the assigned slot space if dual slot is used, so if I delete second slot I will not have to worry about FW size.

Thanks again and have a nice day.

Pedro.
