Matter: chip-tool pairing ble-wifi failing with Abort trap: 6 on macOS

chip-tool can be used for commissioning ESP32 with Matter.

macOS users may face the following error with iTerm:

chip-tool interactive start

pairing ble-wifi 0x7283 SSID PASS PIN 3840
..[FP] Validating NOC chain
..[FP] NOC chain validation successful
..[FP] Added new fabric at index: 0x1
Abort trap: 6

It’s necessary to grant access to Bluetooth to apps launched from iTerm.

Click System SettingsPrivacy & Security. Select Bluetooth. Click +, Select Applications, and find iTerm.

Close and open iTerm. The problem with “trap 6” should be gone.

Just do not forget to install Bluetooth Central Matter Client Developer mode profile. Otherwise the provisioning will fail with UUID problem.
