I have a BBB with debian-8.4-iot downloaded from beagleboard.org. I changed the wifi tethering ssid and password by the following commands:
connmanctl tether wifi off
Disabled tethering for wifi
#connmanctl tether wifi on mybbb 1234567890
Wifi SSID set
Wifi passphrase set
I confirmed that I can see the new ssid by my laptop wifi scanner. I also confirmed settings in /var/lib/connman/settings was changed correctly.
After rebooting the BBB, the ssid was reverted to BeagleBone-A4FD. The ‘Tethering.Identifier’ setting in /var/lib/connman/settings was also changed to BeagleBone-A4FD,
but the ‘Tethering.Passphrase’ setting was reserved.
Any one know how to reserve tethering SSID over rebooting? Thanks!
