Problem in updating firmware via BLE with stm32wb55 and android phone

[Vleon.1]

hi community, i'm getting trouble in updating firmware over the air via BLE, i followed the AN5247 for updating firmware via ST BLE SENSOR APP but it didn't work properly. I'm not able to load the new firmware in my nucleo, the board doesn't seems to be visbile in the new phase of discovering on my phone.

I looked at almost everything on internet but i didn't mange to make it works, any help would be appreciate, thanks.

I seem to have the same issue, on the app I get Start Scanning and then "Node not found". Did you happen to find a solution!

So I took a step back first and focused on the BLE_p2pServer_ota and BLE_heartrate_ota connected with the BT sensor app on phone. I then hit a problem that the BLE_p2pServer would not advertise and thus I could not connect to it. Long story short I figure I needed to also install the BLE_Ota application. This gives you the OTA advertising. From there I can install heartrate application and P2Pserver via the app, not problems.
