First, I would like to send data from a child to the root of the network but the roots don't receive the data and logs are:
Code: Select all
I (12991) wifi: new:<7,1>, old:<7,1>, ap:<7,1>, sta:<7,0>, prof:7
I (13001) wifi: station: 3c:71:bf:0d:7e:18 join, AID=1, bgn, 40U
I (13031) mesh: 1185[recv]invalid child 3c:71:bf:0d:7e:18
I (13031) mesh: 1185[recv]invalid child 3c:71:bf:0d:7e:18
I (13051) mesh: 1185[recv]invalid child 3c:71:bf:0d:7e:18
I (13051) mesh: 1185[recv]invalid child 3c:71:bf:0d:7e:18
I (13051) mesh: 1674[XON]async, from child 3c:71:bf:0d:7e:18
I (13101) mesh: 1185[recv]invalid child 3c:71:bf:0d:7e:18
I (13101) mesh: 1185[recv]invalid child 3c:71:bf:0d:7e:18
I (13101) mesh: 1674[XON]async, from child 3c:71:bf:0d:7e:18
here are the interesting snippets of code:
send data
Code: Select all
void send(){
while(true){

}
}

continue;
}else{

}
}
}
Code: Select all

}
break;

mesh_layer = connected->self_layer;
