[pavan_142297]

Hello all,

I am using the BLE app UART code. I m trying to connect one plus through BLE connection. but nordic devkit  BLE is not visible.

I am using the default configuration without any changes.

Hi

Using a phone's default Bluetooth scan settings (in the settings menu), it will not show all devices that are advertising over BLE, but only a select few, like HIDs, headphones, etc. You can try downloading the nRFConnect app on your OnePlus and make sure location services are enabled. You should be able to see way more devices, includling the ble_app_uart device.

Are you using a development kit or a custom board? Are you sure that the device has been programmed, and if so, that it has been programmed with both the application code and the SoftDevice?

Best regards,

Simon

Hi Simonr,

I am using a custom design board using nrf52810. yes, the device is programmed with both files softdevice and application file. also, BLE is visible to oppo phone. I am using nrfconnect in mobile to connect with the board. but BLE is not visible in nrfconnect app.

Hi Simonr,

BLE DEVICE is visible only on ble 5.0 specified mobiles. But not visible on Ble 5.2 or BLE 4 SPECIFIED MOBILE.

Hi

What are these BLE 5.2 and BLE 4 mobile devices? What SDK version are you using? I don't think any phones should be unable to scan for a default version of the ble_app_uart application.
