Thingy:91 HW not supporting FOTA update of nRF52?

[Augusta1565]

My understanding is that Thingy:91 HW doesn’t support FOTA update of nRF52 from nRF91 since the reset control line isn’t connected from nRF91 towards nRF52. My understanding is that a controlled reset of nRF52 is needed after update of the nRF52 SW.

 

Is my understanding correct?

Hi, you are correct, the Thingy:91 does not support FOTA update of the nRF52.

Hi Heidi,

Can you clarify what is lacking to support firmware update of nRF52 from nRF9160 on Thingy91. We need that information going forward with our project.

Thanks / Bjorn

It's not possible because we don't have SW support for it today.

Regarding resetting the nRF52 after an update, you could always do a soft reset.
