If you get this error, your device is disconected

keskink commented 2 weeks ago

No way. 1- my app is not new developing. Codes are running with 1.20.8 w/o any problem. I upgraded to 1.32.8 in few days. 2- if I set withoutResponse=false (or use default setting), it is working fine.

Thanks in advance

chipweinberger commented 2 weeks ago

okay.

keskink commented 2 weeks ago

This issue should not close. the issue still exists when I set withoutResponse = true. I need to use this withoutResponse.

should fix this issue.

chipweinberger commented 2 weeks ago

What is "the issue"?

keskink commented 2 weeks ago

same issue, nothing changed. withoutResponse assuming connection closed. But device not disconnected. When I set withoutResponse=false it is working. but I need to use withoutResponse=true.

chipweinberger commented 2 weeks ago

how do you know the device is not disconnected?

chipweinberger commented 2 weeks ago

also, can you find the first version where this started becoming a problem?

keskink commented 2 weeks ago

I know is not disconnect because, device working and don't send disconnect commend. and same code working with 1.20.8 and I don't know where the issue started.

chipweinberger commented 2 weeks ago

please determine the first version with problems.

chipweinberger commented 1 week ago
