Can I figure out which characteristic was set notifying in onUpdatesEnabled callback?

Novice question.

My device has four characteristics. Each has BLE_GATT_CHAR_PROPERTIES_NOTIFY propertie. I want to figure out which characteristic was set notifying in onUpdatesEnabled callback from charHandle argument.

I tried to compare a charHandle argument with mychar.getValueAttribute().getHandle(). But no match occurred.

So I checked with DEBUG print. Results are follows:

mychargetValueAttribute().getHandle()charHandle-argument
#1015
#2119
#3222
#4325

Am I missing something?

I use RedBearLab BLE Nano (Nordic nRF51822).

You've uncovered a major issue with the Nordic port. We'll track it at https://github.com/mbedmicro/nRF51822/issues/20 We expect to provide a fix within a couple of days. Thanks so much for reporting this.

Accepted Answer

Takashi,

A fix has been pushed to the develop branch of BLE_API/nRF51822. Could you please build against that and retest?

thanks,

Thank you for your quick and kind response. I'll retest soon. Ah. You've changed two files: nRF51GattServer.cpp and nRF51GattServer.h, for the issue #20. Is this correct?

Rohit,

Result of retesting is good. A return value of getHandle() is equal to an argument value of callback.

Thanks so much.
