No BLE devices show up on scan

[MadhavP]

Hi,

I am running node-red on macOS (Monterey 12.1). I am new to node-red and simply want to read BLE sensor data from a peripheral (TI LPSTK-CC1352R) on my macbook.

I am using the node-red-contrib-generic-ble 4.0.3, it installs fine (Screenshot below), I follow the instructions for configuring the 'Generic BLE Out' node.

Here's the issue. On enabling 'BLE Scanning' nothing shows up ! My terminal window does say '[info] [GenericBLE] Start BLE scanning' (Screenshot below) but no peripheral device comes up in the 'Scan Result' drop-down menu. The BLE sensor node is working. I verified by finding it on the Bluetooth app (LightBlue) so sensor is transmitting.

Could someone kindly point how to solve this issue ? Thanks.

I have checked that both the Terminal and Web Browser have the permission to use Bluetooth in the security and privacy setting of the laptop.
