CC2340R5: Notification is not received

Manjunath Mandya

Part Number: CC2340R5

Hi,

I added a new service and wanted to add notification using CCCD. Iam not able to enable notification.

When i enable notificaiton from TI simple link app, control reaches to GATTServApp_ProcessCCCWriteReq function after which

the app gets disconnected from peripheral ( looks its crashing ).

How to resolve this issue. When i try to single step, the CCS debugger displays control at GATTServApp_ProcessCharCfg

( I have used optimization level as 1 under compiler configuration ).

My new service attribute table

When i enable notification button on SimpleLink app i get control here

My Notification sending code

Could you let me know how to resolve this issue.

Thanks

Hi,

I think they might be a problem in how you are adding the service and initializing the Client Characteristic configuration attributes.

Can you take a look at the SimpleGattProfile_addService@simple_gatt_profile.c:262 and can you confirm you are adding the service the same way?

Please do not expect answer before May 21st as May 17th and May 20th are public holiday here.

Regards

Hi Manjunath,

For sanity check could you review the compilations warnings (if any)?
Additionally, can you double check with Btool GATT Table discovery that your GATT table contains the expected elements. Please check this section of the User's Guide for guidance: TI BLE5-Stack Quick Start — SimpleLink CC23xx SDK BLE5-Stack User's Guide 3.02.04.00 documentation)
