Connection Issue

I am working to get the Ollie up and running on a windows 10 machine. I have installed node, node-gyp, noble, sphero noble, and their dependencies. I can successfully find Bluetooth connections via ./advertisement-discovery.js, and can connect to peripherals using ./peripheral-explorer.js, however when I run the basic connection example with the Ollie's address, I get the following output:

C:\Users\IronLab\Desktop\test\node_modules\sphero\lib\adaptors\ble.js:404 return this._connectedService(serviceId).characteristics; ^

TypeError: Cannot read property 'characteristics' of null at Adaptor._connectedCharacteristics (C:\Users\IronLab\Desktop\test\node_modules\sphero\lib\adaptors\ble.js:404:43) at Adaptor._connectCharacteristic (C:\Users\IronLab\Desktop\test\node_modules\sphero\lib\adaptors\ble.js:357:12) at C:\Users\IronLab\Desktop\test\node_modules\sphero\lib\adaptors\ble.js:302:12 at Adaptor._connectService (C:\Users\IronLab\Desktop\test\node_modules\sphero\lib\adaptors\ble.js:338:5) at C:\Users\IronLab\Desktop\test\node_modules\sphero\lib\adaptors\ble.js:300:10 at Adaptor._connectBLE (C:\Users\IronLab\Desktop\test\node_modules\sphero\lib\adaptors\ble.js:324:5) at Adaptor.getCharacteristic (C:\Users\IronLab\Desktop\test\node_modules\sphero\lib\adaptors\ble.js:299:8) at Adaptor.writeServiceCharacteristic (C:\Users\IronLab\Desktop\test\node_modules\sphero\lib\adaptors\ble.js:274:8) at Adaptor.setTXPower (C:\Users\IronLab\Desktop\test\node_modules\sphero\lib\adaptors\ble.js:203:8) at C:\Users\IronLab\Desktop\test\node_modules\sphero\lib\adaptors\ble.js:156:10

Am I missing an extra dependency?

Hi @DarrenGuinness what is your output from /advertisement-discovery.js for your Ollie?

Also, are you able to run peripheral-explorer.js using the Ollie's ID? What is the output?

[DarrenGuinness]

advertisement-discovery output:

node ./advertisement-discovery.js peripheral discovered (ed9a8071f1fd with address <ed:9a:80:71:f1:fd, random>, connectable true, RSSI -59: hello my local name is: 2B-F1FD can I interest you in any of the following advertised services: ["22bb746f2ba075542d6f726568705327"] my TX power level is: -10

--------------------------End of output----------------------------

I am able to run the peripheral-explorer script using the Ollie id. The output is as follows:

Hi @DarrenGuinness I see that no services/characteristics were found for that ID, similar to the problem here https://github.com/orbotix/sphero.js/issues/49 except you are on Windows. Hmm.

Which Bluetooth LE adaptor are you using?

[deadprogram]

Hello @DarrenGuinness I saw this issue on Noble https://github.com/sandeepmistry/noble/issues/372 perhaps you can try downgrading bluetooth-hci-socket to v0.4.2 as suggested there?

Hi @deadprogram I am suffering exactly the same issue on Raspberry Pi (with Raspbian Jessi). I downgraded bluetooth-hci-socket to v0.4.2 but it continues failing with same error. @DarrenGuinness, did it work for you?

[DarrenGuinness]

I ended up switching to ubuntu 14.04. After that the setup and install was a cinch.

@deadprogram , @debu66er

Hi I am having exactly the same problem/stacj on Rpi3 -- here is the output when I run peripheral-explorer -- I installed sphero and noble as of today, even though unlike @DarrenGuinness I do get a non-empty "services and characteristics" -- -- any suggestions I may want to try?
