How to connect multiple BLE HC 08 to nRF52832 (as central) using UART communication.

I am trying to connect multiple BLE HC 08 devices to nRF52832 DK but I am not getting how to configure the nRF52832 as central

  • There is plenty of central examples available in SDK. Have you tried modifying them?

  • If you want to use Nordic BLE UART Service (NUS) communication outside simple SDK example you will need to develop your FW (based on \examples\ble_central\ble_app_uart_c example from nRF5 SDK), not just configure something. If you want to connect to multiple peers you can configure and manage multiple parallel connections in your FW, still \examples\ble_central\ble_app_uart_c example is the best baseline. If you would like to have mix of such devices which should be able to "randomly" connect in any topology then you would need to use the latest S132 SD V4.x which allows multiple parallel GAP Peripheral connections and implement both GAP Central (+ GATT Client) and GAP Peripheral (+ GATT Server) configurations (in multiple "slots") so when two devices "meet" they will work together. But this is going into implementation details...
