Part Number: CC2640

Tool/software: Code Composer Studio

Hello

I use CC2640 to develope BLE central device and use 3-party chip (Nordic )to be BLE pierpherl .And the CC2640 could not receive notify event (ATT_HANDLE_VALUE_NOTI )from 3-party decice. While initialing GATT Client,  CC2640 has registered related event , please refer to the flowing code .

// Register to receive incoming ATT Indications/Notifications
  GATT_RegisterForInd(selfEntity);
// Register for GATT local events and ATT Responses pending for transmission
  GATT_RegisterForMsgs(selfEntity);

Then CC2640 should receive ATT_HANDLE_VALUE_NOTI in SimpleBLECentral_processGATTMsg(), but gateway does not receive the event.
I use LightBlue app to connect 3-party device,  the app could receive notification event.  Please help on the issue, thank you.

    Hello,

    I use packet sniffer to sniffer cc2640, but  there's no log.

    I did discover characteristics on server , and  I try to enable notify attribute by writing handle 0 x 0100 , and it works . Now  cc2640 could receive notify event.

    But I would like to ask if it's correct solution to enable notify event.  Thanks for your reply.
