BLE Uart Example Data Link Layer

[Moritz Blumenthal]

Dear Nordic Support,

does the BLE Uart example (SKD 14.2) inlcude any data link layer machnisms, for example error detection & correction, collision avoidance?

I implemented an echo mechnism for a type approval software. The BLE peripheral device sends an echo request to the central device, which should respond with an echo.

Sometimes (e.g. in 18 of ~ 5400 cases ) the central device does receive and echo request, but the peripheral device does not receive an echo.

I am using the soft device 132.

Kind regards,

Moritz Blumenthal

Hi Kenneth,

thanks for your information. The slave latency is defined as 0 in main.c An echo request is send once a second and some addition data is send each 500 ms.

I reviewd the uart interface in my application an it looks like the data was lost there. So far it is running without any loss.
