Please check out this page where common Samsung Galaxy A10 issues are dealt with. Please go through the ones that can make the Bluetooth capabilities suffer, and see if there's any change. In the meantime, I'll see if I can get my hands on one myself to see if I can recreate the problem here on our end.

Best regards,

Simon

Hi Simon. Sorry it took so long to get back to you. It is not appearing with regardless of what firmware is loaded on it. The SDK version is 15.3.

Are you able to discover other ble_app examples on nRFConnect with it? You can try flashing it with the ble_app_hids_keyboard example and see if you can discover it using the phone's own Bluetooth app. Also, what SDK version are you using?

Best regards,

Simon

I have tried all the above and still had no luck

Thanks for clarifying your predicament! Can you please go through these "fixes" for the Samsung Galaxy Bluetooth issues? Even though it says S10, the procedure should be rather similar on the A10 as well. In the meantime, I'll ask internally if anyone has had similar experiences using the Galaxy A10.

Best regards,

Simon

hi simon, yes this is a sparkfun nrf52832 breakout board. The board is advertising, it can be seen on the bluetooth menu of another phone, i can check with a 3rd phone if need be but I'm fairly certain that is not the problem. The chip is programmed with the ble_app_hrs example. The galaxy A10 can see other devices with the nRF connect and can see my personal phone and some other bluetooth devices, just not the board. This is where i'm stumped. I restarted the phone, updated the software, turned bluetooth on and off, enabled bluetooth HCI snoop log, enabled show ble devices without names, all without luck. Not sure where to go next. I'll see if I can find it on a 3rd phone

Are you working on an nRF52 Development Kit, or is this a custom board? Are you sure the nRF52832 is advertising at all? Did you program the chip with the ble_app_hrs example?

Best regards,

Simon

Yes. I went into settings and gave the app full permissions manually. I'm pretty sure You don't need to request permission to access Bluetooth as it is a normal permission. Nonetheless, I have accepted any request given on said device. And yes i have disconnected the other phone from the nrf device.

Just so the cart is behind the horse so to speak.

Does the app have BT access authorization?
And have you disconnected the other phone from the nrf device?
