ESP32 Scan for BLE devices with in mesh network - bluetooth-lowenergy

Question

I'm working on a project where I have 3 esp32s in a mesh network that each scans for a 4th to 5th esp32 that inst in the mesh network to get the RSSI of the BLE advertisement.
I made code where I'm doing these 2 parts separately but then I try to merge them it doesn't work.
Could it be that its not possible to scan for a BLE advertisement while in a Mesh network?
