Services are not discoverable

[parkboo]

Hello,

Thank you for your awesome project.
I'm struggling with an issue.

My developing environment is:

• Raspberry pi (Raspbian) with kernel 3.10.24+ ( as peripheral )
• IOGear Bluetooth dongle GBU521
• iPhone 5 ( as Central )
• node 0.10.24

I wrote a node.js test code with 2 services but these services are not discoverable like this screen shot :

(pi-parkboo is my rpi's name)

I think my dongle works correctly because when I wrote a very simple BLE advertising code with C it works perfectly and BLE scanner can catch there are services.

My code snippet is : https://gist.github.com/parkboo/7277ccda610323a95027

Hi Parkboo,

Maybe it's because you ask to advertise a service uuid 1112 :

bleno.startAdvertising('pi-test', ['1112']);

And you don't declare it anywhere. The two services you declare are '180a' and '01010101010101010101010101010101'...

Try to replace the code above by :

bleno.startAdvertising('pi-test', ['180a']);

or

bleno.startAdvertising('pi-test', ['01010101010101010101010101010101']);

And I'm not sure you can use the same characteristic instance in two different services, but maybe I'm wrong...

Hope it helps ;)

@parkboo code snippet worked for me the first time:

Which version of bleno and BlueZ are you using? It might be related to issue #18.

Thanks for helping out @FredericRuaudel !

@FredericRuaudel
Oh, that was my mistake. I've changed the uuid to '01010101010101010101010101010101' but the service uuid is still not visible. :(

@sandeepmistry
My BlueZ version is 4.99-2 (via dpkg --status bluez)
I'll try the latest BlueZ and 3.06 kernel also.

Thank you all, guys.

@parkboo I'm running BlueZ 4.99 on my RPi, no need to upgrade. I would try to update your kernel, mine is 3.6.11+.

Which version of bleno are you using?

[parkboo]

@sandeepmistry My bleno version is 0.1.1. I installed bleno with npm just a few days ago.

[sandeepmistry]

Ok, that's good you'll have this 67b9bf1. I'm running Github master.

Just to confirm, your issue is your not seeing the advertised service UUID? Like in my screenshot.

[parkboo]

@sandeepmistry Yes, exactly.

[parkboo]

@sandeepmistry I've downgraded firmware to 3.6.11+ and everything works fine!

[pdominique]

parkboo > how did you downgrade the firmware (kernel)? I have similar issues with Bleno.

[parkboo]

@pdominique Visit https://github.com/Hexxeh/rpi-firmware/commits/ and get the commit id of firmware what you want and pass it as an argument of rpi-update.
For me,

sudo rpi-update f48e3c15504300c2ac7b677c295dfa6a0ed2121a

[sandeepmistry]

Thanks @parkboo I'll get a another SD setup for my RPi to try out.
