no logs

can you repro is on the example app?

logs would be really useful

also, can you add a lot of print statements to the connect & disconnect code in FBP so we can see where it gets stuck and who still has the lock?

The main problem is that I wanted to connect without the device being turned on (and w/o scan). As you know, when I want to connect without the device being turned on, there is no problem. When the device is turned on, it connects automatically. But, when I disconnect without connecting, the command hangs.

I don't use example, because of, I am using my app in connect w/o scan mode.

it is working good in this condition. I think no issue after this.

await this.device.connect(autoConnect: true, mtu: null); . . . onDoubleTap: () async { await fxRdt.device.disconnect(); print("${fxRdt.name} ddd disconnected"); await fxRdt.connect(); print("${fxRdt.name} ccc connected"); },

what you describe should work.

you should be able to cancel an in-progress connection attempt using disconnect

since it seems you decided to use autoconnect instead, im going to close this since.
