Problem with the simulator, and bluetooth connection

Hi,

I would like to use a existing companion application on Android (not developed by me) to discuss with my connectIQ app on simulator, to find where are my bugs.

I am not very familiar with communications, then I am trying the sample comm to see what happen. But it doesn't work :

- I have connected my phone with USB and have allowed USB debugging

- I have downloaded on windows the adb tools, and have lauched adb with the command "adb forward tcp:7381 tcp:7381",

- I have then my phone listed with the command "adb devices -l".

- I have lauched, on Visual Studio, the connect IQ sample comm, but the simulator, when I make "adb connection --> start", give an error message with "ADB disconnected"

And of course, the app, when I try to send "Hello Word", is saying "there is no data connection, please connect .....run the command forward tcp:7381 tcp:7381"

Could someone help me ?? Thanks and sorry for my poor english

I don't know if the method you tried is supported in the Garmin Simulator but they do support a Bluetooth dongle and toolkit to allow the simulator to talk over Bluetooth. You might want to look into that instead.

I got the dongle and toolkit which I planned on using until I found out the watches can only listen for devices to pair too. It can't initiate a pairing process :-(

For companion apps and the SIM you use a USB cable, the app must be set for "tethering" and the companion app needs to "know" about the CIQ app.

The Dongle is used for Toybox.BluetoothLowEnergey and not for talking to GCM and companion apps.

OK, but what is tethering ? My companion app was not developed by me, and I don't have source code

And, using the comm sample as I said, what is wrong ? I don't use any app, but Connect IQ is working on my phone

Thanks

"Teathering" is that it uses the USB cable and not BT the way I understand it.

I really doubt you can just use someone else's companion app

Yes, it's r.485 and the developer add something for my app (sailing with waypoints) a few years ago, and now, with the last SDK, on some models, some users has reported crash when using it, I would find where is the problem

Do I need to have source code to make r.485 teathered ?

Why not ask r.485 for help with this?

Yes, I could, but this is my app which is crashing since my update, and I guess he could not do something

I could but I would also like to learn what I do with communications

But yes I will
