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

Running one ble_app_uart example (peripheral) and two centrals with your code, when turning off power on one central the peripheral connects to the other central without doing any resets. Seems there is no problem here or am I doing it wrong?

Hi Ole, sorry to confuse you. The code I uploaded before is based on SDK10 multilink example and the problem of the handover does not exist. But I have some difficulty for integrated it together with the UART. I spent some time to restudy the code and did some changes on the SDK8 and I think the handover issue has just been fixed. We can close this topic now. Thanks you so much for your time and kindly help.
