Some of the Develco SMSZB-120 in my network fail to update via OTA

What happened?

I have 5 smoke sensors Frient Develco SMSZB-120.

Recently, I received a notification for all of them that there was an update via OTA available. I decided to update all of them.

However, I cannot understand why there are only 2 devices which start the OTA process but then the update fails after some time. See pictures below for one of them where OTA starts but at some point I receive an error message that OTA did not complete:

Which ends into this:

This still happens after re-trying in other times, or only doing the OTA for one of the 2 devices per time and putting both the devices close to the antenna (like 2 meters plain sight).

What did you expect to happen?

I expect all devices should successfully finish the OTA process.

Try temporarily moving them closer to the coordinator, mine constantly had timeouts why trying to update. I had to move it close and swap to a fresh battery for it to succeed.

Thank you, I had tried to place them very close to the coordinator (as I wrote in my original message) but it did not help. Changing the battery (despite the smoke alarm indicating to be in good state) got the job done.
