CC2650MODA: Unable to connect CC2650MODA from Android device

Part Number: CC2650MODA

Hi,

We got our first custom board designed with CC2650MODA and we have a problem in connecting to the device from Android phone.

I am getting GATT ERROR 133.

We had the same issue when we directly soldered the pins to the MODA as per

I have not received any support from TI on this issue. Could you please help us understand the problem?

Thank you,

Bharath

    Hi Bharath,

    I have a few questions to help with debugging this:

    1. If you run the same code on a TI dev kit do you have any issues? This will help determine if its a hardware issue.
    2. Do you have issues connecting to non-Android devices? This will help determine if its an Android issue.
    3. Where does GATT ERROR 133 come from - the phone or the TI device?
    4. What example app & sdk version are you using?
    5. Can you send a sniffer capture of this behavior?

    Hi Rachel,

    Thanks for the reply.

    1) I do not see any issues running the same code on the CC2650LaunchXL board. But I have come across the same problem in two MODA modules.

    2) I am able to connect to android device on LaunchXL. Out of three custom boards, one is connecting and other two are not.

    3) GATT ERROR is seen on the android phone when I try connecting to the costum board.

    4) I am using SimpleBLEPeripheral example and SDK 'ble_sdk_2_02_01_18'.

    5) I do not have any sniffer to capture the behavior.

    Thank you,

    Bharath
