Other Parts Discussed in Thread: CC2540

I use keyfobdemo as the base to develop a samrt deived with CC2540. When i develop an App on IOS, I find a strange question. In my app, i read service attribute after connectted, sometime the attribute is NULL, but usally it is OK. What is the matter? Problem of CC2540 or IOS app? Help me please, Thanks.

Hello Wei,

If this is a custom app on iOS, you should be able to trace the problem when it does a BLEServiceInfo call. This periodic problem would require a lot more details to resolve. For one thing, is the connection being lost when you get a NULL?

Thanks,
