Hello!
1)There is problem with nrf_ble_uart. On sdk 4.4 work well, but sdk 5.1 the same code is not working. What changes were made in the sdk or maybe there is a ready example nrf_uart under the new sdk? 1.1) Why not install sdk 4.4 on win8.1 (nRF51 SDK Wizard ended prematurely)?
- What is the maximum speed of the uart in nrf51822?
