CC2340R2: How to turn on BLE again after shut down cc2340

Tool/software:

Hi Experts,

I'm using cc2340R22 and trying to do power saving.

After being shut down, everything is ok, but when I power on again and PowerLPF3_releaseLatches(), I couldn't see the BLE advertising.

Anything I should do wake up RF?

Thanks in advanced.

    Hello,

    Thanks for reaching out! That is unusual behavior, as it shouldn't stop advertising unless specified so. I have a few questions:

    Are you using any of the examples from the SDK?

    What SDK version are you using?

    How are you verifying that the device is not advertising?

    Best Regards,

    Tarek

    Hi Tarek
    I'm using basic_ble of simplelink_lowpower_f3_sdk_8_20_00_119.
    Before shut down, BLEAppUtil_advStop was called, and power on again and PowerLPF3_releaseLatches(), BLEAppUtil_advStart() was called. However, I didn't see any bevice name from APP .

    With the same steps, entering standby mode and then back, it's ok.

    Hello,

    I'm looking into this. In the mean time, is this also seen on the newest SDK?

    Best Regards,

    Hello,

    Could you also provide any changes you have made to the default example? And as mentioned, if you could test it on the newest SDK, that will make the process of pinpointing the issue much easier.
