Android Question best way how to restart bluetooth connection

[petr4ppc]

Dear friends, I am finding solution, how to reconnect bluetooth conenction with click on button.

I have serialservice, where I am using AStream

After connecting to bt device I am trying for reconnect this:

Sleep(1500)
serialservice.AStream.Close   
Sleep(500)           
Serial1.Connect(macadd)
serialservice.AStream.Initialize(Serial1.InputStream,  Serial1.OutputStream, "AStream")

with this this solution the connection between bt devices is OK, but the data I cant send and receive.

How can I complete restart bluetooth connection with button?Please?
Thank you

You don't need these Sleep methods. They will only cause problems. Use CallSubPlus if you want to add a short delay.

AStream should be private and only accessed from the serialService. This way the events will be raised in the correct module.

Erel and dear friends,

I am finding solution, but I have solved only 50 percent of this task.

Situation:
1. I am creating simple bluetooth connection as in ADMIN example = everything is OK
2. This connection I interrupted with some way, for eexample I switch off the power of bluetooth in second device
3. If I restart the bluetooth connection from the app then I get this trouble=

I can send data from APP to second BT device, but I can not send data from BT device to APP. The APP is not starting the ASTREAM listening.
If I switch off the app and then run again, everything is OK. Only after restart I can send data but not receive...

Please how can I start or initialize listening of seriál port in the app?

Thank you very much

You need to handle AStream error and terminated events. If the connection has broken then you need to start a new connection. There is nothing special that needs to be done.
