NRF51822 sensor (S110) reconnection between different APs (S120)

Hi, I am working on a project that the ble sensor will be mobile. I load mutiple nrf51822 with the softdevice S120 working as APs and place them in different places to extend its coverage. I load one nrf51822 with the softdevice S110 acting as the sensor. I expect it will automatically connect to the closest AP when it drops from the prvious AP. However, the sensor will stay in disconnected unless i reset the sensor or the closest AP. Any idea what causes that? Sensor: SDK Softdevice 8.0.0 + ble peripheral UART example AP: SDK softdevice 2.1.0 + ble central uart example

Thanks Ole Bauck, I prefer to use S120 for the AP as I don't want it to be discovered by any other devices. I noticed the SDK 10 has S120 example. I have tried both ble_app_uart_c and ble_app_multilink_central in the ble_central example. Both examples works well, but when I tried to integrated them together, I always end up some problem. I also noticed that there is a ser_s120_uart example under the ble_app_multilink_central. Does this example will do the multilink+UART? I also tried this example but it does not connect to the peripheral and also does not show up anything on the terminal. When I enable the app log support, it complains about the missing link. Is there a working solution for S120? Thanks very much! Jack
