[binary-dep] WARN Pre-compiled module is missing: usb

[sanderblue]

Using recommended USB BLE device

Output follows with:

This might be caused by any of the following:

1. The binary is platform specific and cannot be compiled for OpenWRT.
2. A pre-compiled binary has not yet been generated for this module.
3. The binary didn't compile correctly for the platform that you're developing on.
    It's possible that the binary is Linux-only or even OpenWRT specific,
    try npm installing with "--force" and rerun your deployment command.

Strange that I haven't seen this before, but sure enough, it's as a result of https://github.com/sandeepmistry/node-bluetooth-hci-socket.

It's actually not needed because it's an optional dependency for windows/linux but super annoying.

Anyone that sees this should just ignore it for now.

[sanderblue]

@johnnyman727 Yup, thanks for the reply. I had noticed this was negligible, but like you said, still a bit annoying. I was seeing that warning simultaneously with a bluetooth-hci-socket and just posted them as separate issues.

Here's the bluetooth-hci-socket thread. @rwaldron quickly took care of the bluetooth-hci-socket issue so I closed that one.

Seeing this also when attempting to use the usb package. Happy for a pointer to instructions on how to hack around and get this working if there are some :)

[johnnyman727]

@DamonOehlman usb binary dep support is currently hung on tessel/openwrt-tessel#36. If you want to get your hands dirty and investigate, that would be 💯

I'm seeing this when not even attempting to use the usb package. I can't get the t2 init hello world app to work.

[sanderblue]

@aaronshaf This issue shouldn't affect you're ability to run t2 init. If you follow this guide to get started, you should be just fine. If you end up seeing any errors at any step, try to diagnose then create a new issue explaining what error you're seeing and at what step the error happened.

The Tessel team does a good job at responding to issues and helping out.

[sanderblue]

@johnnyman727 I'm going to close this issue given it's negligible and really shouldn't affect anyone doing basic dev work with Tessel 2. I've been using a 3rd party BLE module just fine with USB ports on two different Tessels.

[sanderblue]

@aaronshaf also, try running t2 update and see if that fixes your problem.

[rwaldron]

@sanderblue ok to close then?

[sanderblue]

@rwaldron sorry, I got distracted. Yep, I'll close now

[rwaldron]

Thank you :)
