First Connect works, the second throws an error

[amihaylo]

Hi Pires, thanks for providing the obd api it's helped me tons!

I hope this is right way of going about asking for help, if not please redirect me and I will do so. I have had the issue for a while and am out of ideas which is why I turned to you in hopes of figuring out a solution to my problem.

So the first time I connect to OBD I have no issues and read the data just fine. If I however disconnect and try to reconnect, it fails and throws the following error: W/System.err: com.github.pires.obd.exceptions.UnableToConnectException: Error running 01 46, response: ...UNABLETOCONNECT

After that failed attempt, if I try to reconnect again it works.

After every connection I make sure to close it with the Close Command as such:

CloseCommand closeCommand = new CloseCommand();
closeCommand.run(this.mmSocket.getInputStream(), this.mmSocket.getOutputStream());

Is there something I am not doing correctly? Possibly closing the streams? If so how would I go about doing that?

It may be something with your device.

I've tried it with a number of devices, same error persists. Any ideas what else the issue may be?

01 46 is Ambient Air Temperature. what happened to all the AT commands needed to reconnect?

Perhaps I'm not doing it properly, but upon every reconnect I initialize with the following commands:

new EchoOffCommand().run(this.mmSocket.getInputStream(), this.mmSocket.getOutputStream());
new LineFeedOffCommand().run(this.mmSocket.getInputStream(), this.mmSocket.getOutputStream());
new TimeoutCommand(125).run(this.mmSocket.getInputStream(), this.mmSocket.getOutputStream()); 
new SelectProtocolCommand(ObdProtocols.AUTO).run(this.mmSocket.getInputStream(), this.mmSocket.getOutputStream());
