ble.NewConnection sometimes never returns #272
Comments
Could you please include the output of running the command with |
I had the same or at least a very similar problem. As long as the vehicle is nearby the command tesla-control works well, even if repeated thousands of times over a longer time period. With the new code from a few weeks ago the BLE connection is very stable on my system. But when the vehicle is driven away, I got the same error A temporary workaround was to restart the bluetooth service (systemctl restart bluetooth), however this does not last long. Reason for the problem might be a missing 'close' for the underlying socket (socket is created by code from "github.com/go-ble/ble", in ble/linux/hci/socket/socket.go starting lin line 63). I'm neither an expert with Go nor the go-ble package, so I haven't prepared a pull request, but was able to add a few lines of code (see attachment) that look to fix the problem for me. Please add that fix (or a better one) . |
Modified code that includes patch to prevent some errors with BLE interface. See teslamotors/vehicle-command#272 (comment)
I think my issue is different. @sethterashima here are the logs: I'am using a custom Go-App (https://github.com/wimaha/TeslaBleHttpProxy) with this library. So here is a mix of logs from my program and this library. The relevant part starts at 15:34:58. I'm posting some additional log lines to provide context. In the relevant part I added to corresponding function calls to the logs from my program.
So the last message from this library is Edit: Running on Raspberry Pi 3+ |
I think I found the issue. It is in the underlaying bluetooth package. In the ble.go we have the following code: There the ble package is called via In the ble package we have the following code in the Connect function (glatt.go): So and here is a bug. When the vehicle can't be found, normally ctx2 fires bevor ctx, so that the function So we need to propose a pull request on the ble package to solve this bug. |
I've opened a PR on the ble package: go-ble/ble#112 |
@wimaha: I still have the issue described above when the vehicle can't be found with latest code from 'tesla-control' on a Raspberry PI 3B+. After a while the hci0 interface is busy and requires a reset. So far I ended up by switching to BLE package from https://github.com/rigado/ble instead of go-ble/ble. The code for BLE has changed a lot and required minor changes in pkg/connector/ble, but now my issue is gone. To me the ble package from rigado looks to be better, but I'm wondering if that code will end up in go-ble some time in the future. |
Hello,
when there are connection issues the function
ble.NewConnection(ctx, vin)
returns withcontext deadline exceeded
. That's the expected behavior.But after a while (> 15 attempts) the function just never returns.
Any clue what could cause this issue?
The problem also occurs with this #269
