I'm working with ble_app_uart_s130.
Compilation is fine and it works as expected in hardware.
I'm going to add application timer and scheduler.
To do that I have to set checkbox in KEIL Manage Run-Time Environment.
But there is already unresolved error.
It seems it requires another version of softdevice.
Where I can download it, and why KEIL example has unresolved error?
