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

[ldmxhj]

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

It can be discovered by other devices no matter if you use S120 or S130, the centrals will connect if they find the correct uuid in the advertisement packet. ble_app_uart_c with S120 from SDK 10 should work out of the box. I just tested and the peripherals will connect to another central if the one it was connected to is disconnected, which is expected behaviour.

The ser_s120_uart example is a serialized example using uart as serialization interface, see here. You don't have to worry about this.

Combining the ble_app_uart_c example and the ble_app_multilink example may not be straighforward.
