CCS/LAUNCHXL-CC2640R2: Getting the error : 133 GATT ERROR

Tool/software: Code Composer Studio

Hi,

I am using the CC2640R2 Launchpad to run a modified version of the Simple BLE Peripheral and I have trouble with the notify property of a service. 

The connection with the device is stable and I can read and write without any problem. When I use NRF Connect on my android phone and I click on the notify option icon, I get error 133 (0x85): GATT ERROR following by a GATT connection timeout. I've tested multiple connections interval value but it didn't solve the issue. 

I was previously using this notify option on the CC2650 Launchpad with the same Simple BLE Peripheral application and it was working fine. I ported to project to work with BLE5 stack and I did not change the service files under the PROFILES folder of the project.

Do you have any idea why I keep having this problem?

Any help would be appreciated

Seb

Here's a screen shot from NRF Connect:

    Hello,

    GATT ERROR 133 (0x85) is a generic GATT error in Android, so it's hard to tell if this is a phone/app or device side issue. I suggest taking an adb logcat dump and looking for any error descriptions as well as an BLE air packet sniffer trace. That should be a good starting point.

    Best wishes
