Hi,
I'm currently working on an app with the module CYBLE-012011 and I'm facing an annoying issue.
When I'm trying to connect my android to the device with the cySmart app, I'm not able to establish connection. This issue does not occur with all android device.
I have 4 test phones; when I have ran the test only 2 have had a successful connection.
Huawei mate 20 pro : Android 10 -> connection issue
Huawei p20 pro : Android 9 -> connected successfully
Xiaomi remi note 8: Android 9 -> connections issue
Xiaomi mi 9t pro : Android 10 -> connected successfully
Version of BLE compoment topdesign : 3.64 (3.51 also tested with the same results)
I also try to connect the device to a custom Qt app (Huawei mate 20 pro), and I get this log:
W QtBluetoothGatt: Using Android v23 BluetoothDevice.connectGatt()
W QtBluetoothGatt: Unhandled error code on connectionStateChanged: 133 0
W liblowenergyscanner.so: Error: "Error occurred trying to connect to remote device."
I believe that I have tried all possible settings in the component, but I always have the same results.
Am I missing something? Please could you advise.
P.S: I can establish a connection between my samsung tv, and my Huawei mate 20 pro without any problem and with the same app (cySmart app)
Solved! Go to Solution.

Hello,
I had tested the project in CYBLE-022001-01 Module(Currently i don't have the CYBLE-012011 module) with VIVO Y81 smartphone and it is working fine for me. I don't have any issue with connection establishment. Could you please check with the 'BLE_FindMe' code example project in the PSoC Creator ? If you have other module, then please check with that module also.
If you have CY5677 Cypress dongle, please check with it in windows and let me know the observations.
Thanks,
P Yugandhar.

Hello,
I finally found my cy8ble kit (https://www.cypress.com/documentation/development-kitsboards/psoc-6-ble-prototyping-kit-cy8cproto-06... ) with the module : CYBLE-416045-02
With this kit, I don't have any connection issue, seam to be an module related issue. The problem is that the board is already designed, and I already have supply the ble module.
edit: After that, I try with findme exemple, and I don't have connection issue (module CYBLE-012011).
I'll investigate more on that
edit 2: Just a luck, I can't connect with the findme Exemple. I ll try unsolder / resolder the module
Thanks,
Antoine Bureau
