Segmentation Fault 11 Error

[martinabrahams]

Hi, I've been trying to get this to work for days. I'm running;

• Mac OS X 10.15.2
• Node v10.17.0
• XCode 11.3
• MacBook Pro (15-inch, 2019)

When I run a simple echo example I get a segfault 11 error, this error occures regardless of whether I have Bluetooth enabled or disabled. I have attached the relevant system log.

The error appears to relate to the native bindings - BlenoMac::Init(Napi::CallbackInfo const&) + 133 (bleno_mac.mm:52)

I've created a repo to replicate my issue.

I also saw this segmentation fault 11 error when trying to run some bleno related code from a Mac on 10.15.2.

I have since uninstalled and reinstalled bleno-mac, and now when I try to run node service.js, the terminal just hangs there and prints out nothing until I stop with ctrl-c.

So I can no longer reproduce the segmentation fault 11 issue, but I did see that occur this morning before I uninstalled/reinstalled the package.

Bumping this- Anyone have any thoughts on the status of bleno-mac on macOS 10.15.2 ?

I tried using this again and I'm still seeing the terminal hang when I try to run bleno service code via node.

Exactly same here. Before it's seg fault 11 and after I deleted the node_modules and did npm install it just stuck at bleno - echo.

+1 having the same error, it's working on 10.14 but it's not working working on 10.15.2

I am also getting the segmentation fault on 10.15.4.

Rusty on my obj-c but the fix was straightforward. Starting the bluetooth manager immediately starts firing status events, before the event emitter has been properly initialized. Race condition.

I also had to fork this repository and updated bleno dependency to use the following in package.json:

   "bleno": "abandonware/bleno",

Otherwise it won't compile at all with recent node versions.

Hello, I came from Punch Through’s article and I tried to use the "bleno-mac" as dependency. It was a fail.

My initial config was

• macOS 10.15.4
• node -v v13.6.0
• Xcode 11.3.1

I tried to use node v10 and v12 also, but it was an issue with xpc-connection

Also I tried to use @abandonware/bleno, but I got stuck in terminal after run node service.

Finally, this advice was useful to me.

Hopefully, I'll save someone some time.

Hi @kotsaarev, I work at PunchThrough and happen to be the author of that article-

I have not had an opportunity to test bleno-mac yet since this issue was addressed yesterday, but as you've discovered it looks like there is an issue with xpc-connection as well.

I will need to add an update to my article to help anyone trying to use this on the latest macOS. Thanks for sharing the solution you have found.
