UART not working on SDK 13.0.0

[schef]

Hi. When i use ble_app_uart i have problem with my device over uart. It does not response to my commands.

I'm using custom pcb based on nrf52 with nrf UART v2.0 android app. Is there something i'm missing?

Hi,

Does your phone support BLE 4.2 ? If not you will have to do a small modification to the ble_app_uart project. See this answer.

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

Alot. Trying to figure what is happening. Now i have good results. I can see the message in ble_app_uart example. The only modifications are the uart init position and the baudrate and i have disabled BSP beacuse i have no buttons. And the CASE looks like this 3, 0, 0, 0.... But in my project i get 3, 4, 4, 4, 4....

And number 4 is APP_UART_DATA -> like no FIFO is initialised?
