Is connectToService necessary?

[MMIX2009]

I've modified the RFDuino hello example to connect to a LightBlue Bean using the Bean transport UUID. The sketch finds the Bean, but does not connect to the Bean. I get the following error. I noticed that connectToService is not being used even though it is mentioned in the documentation. Is that the missing piece?

Have you tried this again lately? I'm pretty sure this is due to needing to update the way that the Android libraries for BLE are called.

[MMIX2009]

@joshuajnoble the last time I tried I still had an issue with this. Could you let me know if there is anything in the library that if RFDuino-dependent, or is the library suppose to work with any BLE devices given the correct UUIDs?

[joshuajnoble]

It should work with any BLE devices given the correct UUIDs, I've used them with a few different devices and service/characteristic sets. The connectToService method isn't needed any more since you're really just picking the characteristics after having scanned the service.
