Is it possible to perform BLE Scan while participating in an mesh network.

Question

Is it possible to perform BLE Scan using an server (In the Light Switch Demo Example) while participating in a mesh network?

Hi, 
 Yes, it is possible to do other BLE activity whilst participating in the mesh network. Please check out the Beaconing example for a quick demonstration. I also recommend that you read the documentation on Coexistence with other Nordic SDKs .

Hi, 
 Yes, the Beaconing example is for advertisement. You can do scanning but will have to implement it yourself. Please note that SoftDevice activity is prioritized over Mesh activity when running concurrently. From the Coexistence documentation : 
 Concurrent SoftDevice and mesh activity

By design, the SoftDevice activity is prioritized over mesh activity. 
Therefore, you should keep the connection and advertisement intervals 
used by the SoftDevice as large as possible (i.e. infrequent) when 
using Bluetooth low energy connections. If scanning, keep the scan 
duty cycle as low as possible. You should also reduce mesh activity 
while the SoftDevice is doing fast advertising and continue normal 
activity after a connection is established.
