6bcb06e2747542a9a62a54a1f3ce11e6

Known issues

You have to be careful that the payload fits in the MTU

Running without root/sudo

Run the following command in the directory you ran npm install from:

find -path '*bleno*Release/hci-ble' -exec sudo setcap cap_net_raw+eip '{}' \;

This grants bleno's hci-ble binary cap_net_raw privileges, so it can start/stop BLE advertising.

Note: The above command requires setcap to be installed, it can be installed using the following:

  • apt: sudo apt-get install libcap2-bin
  • yum: su -c \'yum install libcap2-bin\'
