CC2652R7: BLE Stack not getting enabled

Part Number: CC2652R7
Other Parts Discussed in Thread: UNIFLASH

Hi,

We are facing BLE issue in our custom hardware with CC2652R7 MCU. We are suspecting BLE stack is not enabled and it is not sending out any beacons. We flashed simple peripheral example code from simplelink_cc13x2_26x2_sdk_5_20_00_52 SDK to verify this issue.

We have customized CC2652R1 Launchpad in which MCU is replaced by CC2652R7 for testing purpose. In this Launchpad simple peripheral code is working fine and we are able to see BLE beacons.

We also flashed timer LED example code on custom hardware and its working as expected.

We have retained the same Launchpad hardware design  in our custom hardware.

out file is flashed on MCU using TI UniFlash.

Need help in debugging this issue.

    Hi,

    Here a few questions to make sure I properly understand the issue and involve the proper team.

    - Is it correct understanding that the same out file works on a TI launchpad but does not work on your custom design?

    - Have you tried to run some RF tests on your custom design using SmartRF Studio?

    Best regards,

    Hi Clement,

    Yes, your understanding is correct. Simple peripheral example code is working fine in Launchpad and not in our custom hardware, but LED example code is working in both the hardware.

    Yes, we tried using SmartRF studio, but we are seeing following error

    Hi,

    Generally speaking, LED example is a significantly less advanced example. This example could work even if the crystals are not working properly or if the antenna is not properly connected to the radio.

    When it comes to SmartRF Studio, I would recommend to make sure to close Uniflash and CCS, or at least to make sure that no any other program accesses the device's COM port. If the issues with SmartRF Studio persist, please open a new thread to get the proper help.

    Best regards,

    We have closed  uniflash and CCS while testing with smartRF studio, still we are seeing this issue. We will open new thread regarding it.

    Thanks
