WPA supplicant service failed when trying to reconnect p2p connection. #21
Comments

Can you reproduce this on latest (vanilla) kernel? You may try to use https://github.com/edison-fw/meta-intel-edison Also it seems you opened quite a few questions here. Perhaps it would make sense to test all and close them here, and open ones that have been reproduced against new meta-intel-edison layer. |
|
Also, why are you calling supplicant directly? Is p2p not supported from connmanctl? |
