Custom BLE app failing to connect to device.

[Balaji.kg]

Hi There,

Custom xamarin bluetooth app [using Plugin.BLE] is failing to connect to the device using ConnectToKnownDeviceAsync approach. User uses tap-to-pair and tries to make a connection to the device.

When user does tap-to-pair we are getting device GUID from the nfc tag payload and trying to connect to the device using ConnectToKnownDeviceAsync method. What we have found is many times the connection fails, if we use nrfConnect app and make a connection and then try with our custom app then it will connect with out any issue.

we want to know what steps we are missing that nrfConnect app is enabling. This issue happens whenever we reboot the device. At this moment we are testing with Android 10.

Any help is highly appreciated.

Thanks,
Balaji

Hi Simon,

sorry for the delay in replaying. I guess the bonding/pairing was not there after pairing the connection is happening. Thanks for your help.
