Hi

I'm trying out the Throughput Example - GATT Notification - Data Outgoing.

When testing the example using CySmart App I'm able to enable the notifications and everything is fine.

But it is not possible to disable the notification with CySmart App. Even writing direct to the Characteristic to disable the notification is not working.

I get following message "Error: gpm.M0117: Write characteristic descriptor timed out"

Hello,

With ATT MTU set to 23 bytes in the BLE component the "GATT Notification-Data Outgoing" project works fine without any issue in the PC CySmart App.

Thanks,

Hello Alfred,

In the Throughput example when we enable the notification it starts sending 512 bytes of information (with 20 bytes in each packet) continuously.  If we disable it should stop sending the data but I found an error which you said in PC CySmart App. There will be an issue in PC CySmart App software we will replicate and let you know once we find the solution. In Android CySmart App it is working fine compared with PC CySmart please check once.

Thanks,

P Yugandhar.

Please check with ATT MTU of 23 bytes in the BLE component.
