serviceuuid N/A - in nrf connect app

[Neshat]

I programmed my beacon with this code: ble_app_beacon.zip

I use nrf connect app to see its signals. nrf connect can find my beacons but it says: serviceUUID : N/A TxpowerLevel N/A

does it mean there is something wrong with my beacons?

It seems you haven't included any service UUIDs or TX power level in your advertisment, so that it is not available is expected. If it is something wrong or not depends if this is something that you want to include or not.

I guess, because there were someone else before me here in this postion and I am not sure what exactly she has done. how can I know if she programmed devices with bootloader? I am a beginner, so sry if I am just wasting your time
