CC2642R: Calling UART2_write for 2 tasks will cause a hardfault
Tool/software:
Hello,team
SDK:simplelink_cc13xx_cc26xx_sdk_7_41_00_17
I call GATT_Notification function, function return is success, however, app received nothing. Whether this is related to the Bluetooth default secure connection?
I want disable secure connection，but sysconfig cannot be set to GAPBOND_SECURE_CONNECTION_NONE。
nRF connect: no notify data was received.
Hi,
Can you please specify which device you are using? Is this for an automotive account?

Please make sure notifications reception is enabled on the phone side:
Please also use a Bluetooth sniffer to check whether the notifications are sent out.

I am afraid this is not possible.

notificaiton is sent out，I give a data stream, help me see the app can not receive the reason
Hi,
Thank you for the additional details.
It looks like you are using GATT_Notification() with 0x0 (FALSE) as "authenticated" parameter. I think this parameter should rather be set to 0x02 - see https://software-dl.ti.com/simplelink/esd/simplelink_cc13xx_cc26xx_sdk/7.40.00.77/exports/docs/ble5stack/ble_user_guide/doxygen/ble/html/group___a_t_t___g_a_t_t.html#gac61599736be6b39a5b18d3ef6eb7a45a
I hope this will help,
Best regards,
