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 see. It is a bit difficult to know. If you attach a programmer you could check the flash area where the bootloader usually is. If your devices have buttons you could try pressing them while doing a reset (reset button or taking the battery out and in) and see if you advertise as a DFU target instead of beacon. Other than that I don't know how to help you sorry :(
