Hi Zachary,

I updated the Spotter to v2.16.2 using the Mac instructions. I used the non-Bristlemouth version since my sticker has a Spotter Icon and not a Bristlemouth Icon. I initially tried the Windows instructions (on Windows 11) and that timed out, but switching to Mac was successful.

After rebooting, I got an error saying the bridge has a “FW\_HW\_MISTMATCH\_ERR”. I thought maybe the Windows method messed something up. I followed the instructions of ([Trouble with flashing firmware - Dev Kit Support - Bristlemouth](https://bristlemouth.discourse.group/t/trouble-with-flashing-firmware/245/8)) and updated the bridge FW to v0.13.4 using the file **[bridge\_release-v0.13.4.zip](https://github.com/bristlemouth/bm_protocol/releases/download/v0.13.4/bridge_release-v0.13.4.zip)**. That was successful, but I encountered the same error after rebooting the Spotter.

I don’t have my dev kit attached to simplify things.
