Diagnostics displaying wrong hotspot name after card swap

[smeakles79]

I have a couple hotspots on and that I keep running (unasserted) to keep the cards synced and up to date. When a field installed hotspot dies, for whatever reason, I've been swapping cards to get them back online rather than wait to resync 10k blocks. With the most recent firmware at latest 2022.01.24. When you swap the cards and run diagnostics on the hotspot, the diagnostics will now show the name of the hotspot and the address from the hotspot the card came from, not the information from the hotspot the card was in. I swapped 2 units, and all 4 had the name/ address swap in diagnostics. Hard closing the app doesn't seem to resolve. I've got the cards from the deployed units back in the donor units. Will update if I see the name/address resolve on those donor units. At least one of the deployed units is earning again, other may still have internet issues)

@Sneak85, I've transferred this issue over to the component that actually performs the Bluetooth diagnostics function. I also suspect that the code here is using a quick shortcut to determine the miner name rather than querying the miner directly. The reason for doing so is likely historical, but it's important enough that this issue might likely not be solved to your liking, because accidentally swapping out SD-cards is a very rare feature, and trying to fix things to support such a swap will likely require dropping a key feature that this code relies on: being able to determine the hotspot name even when the miner itself is broken or not running.

If this issue is truly what I think it is then it's simply a display issue in the diagnostics output. The hotspot itself will know its proper name and will continue to function on the blockchain as normal, under its proper, ECC chip derived identity.

I see a possible mechanism that can be improved, but it will still allow the wrong name to appear in the diagnostics for up to a few minutes after the hotspot reboots and regains its bearings.
