Hi @jerdung !
No, we have more than 500 modules with problem, so I started checking one by one to see what is happening, and in the time of the post, I had tested 50un, now I’m at 300, and all of them are stuck on OTA.
About the App Melody, the app opens, I can connect to the Module, it tells me that are on OTA mode (MelodySmart OT), but the host server with the firmwares appears to be unavailable, so I can’t download or update it or even get out of the OTA mode.
There are some posts about that already:
