BLE connection problem

[DragonAnger]

Hi,

I'm using nrf51822 and ble_app_uart in SDK12.3.

Testing with android app nRF UART v2.0

I have some problem with BLE connection.

First, Sometimes when I tried to connect over BLE,

connection failed with "RX Service Not Found" in android log.

And I tried to connect few times, connected eventually.

Second, When I tried to connect BLE, Android app is fail, but nrf51822 is not.

So, until I reset nrf51288, my app cannot scan this device.

Why this happens? and How I solve this?

Thank you for reading my question!

Hi,

The old UART 2.0 app is deprecated (over 3 years since last update). I strongly recommend using the nRF-Toolbox app, and use the UART function there instead.

Thanks a lot! I'm trying to using nRF-Toolbox but it's hard to understand.
