CC33XX-SOFTWARE: Using CC3301 BLE on Linux

CC33XX-SOFTWARE: Bluetooth Device Scanning Issue with CC3301 on SK-AM62

Part Number: CC33XX-SOFTWARE
Other Parts Discussed in Thread: CC3301, SK-AM62

Tool/software:

Hi,

I am currently using the SK-AM62 processor board running Debian 12 OS with the PSDK version 09.02.01.10. The board has a CC3301 chip, and the CC33xx firmware version is 1.0.0.5 (released on 31 Jul 2024).

Wi-Fi functionality is working properly. However, when scanning for Bluetooth devices, I am unable to detect my phone or laptop. Some peripheral devices are shown. I want to connect to the processor board using my mobile phone app. 

Any guidance or suggestions on how to resolve this issue would be appreciated.

Thanks

Kasun

    Hi,

    Are you using the BlueZ bluetooth stack or another bluetooth stack?

    How are you initiating a scan and what parameters are you using?

    Are you able to find your phone or laptop on other devices?

    Hi Kasun,

    You have me confused. Your original question said you couldnt find your phone and laptop when scanning. But now the bluetoothctl commands you input are for advertising.

    Can you clarify if you are indeed scanning with the CC3301 device or if you are advertising with the device. 

    Best,

    Hi RogelioD,

    Sorry for confusing.

    I want to advertise with sk-am62 and connect to it using a mobile app.

    I can connect to sk-am62 using a ubuntu laptop. But i don't know to transfer data in between.

    My goal is to connect to sk-am62 via a mobile app.

    Regards

    Hi Kasun,

    I believe the main culprit is that you dont have RPA properly setup. If you look at our ble_wifi_provisioning scripts particularly the start_provisioning you can see what commands we use to set up the device particularly you will need to set an IRK. 

    My first recommendation is to run our example and see if you can scan the CC3301 on your phone.

    Hi RogelioD,

    Thank you. I was able to run commands in the demo scripts.

    Now it's working.
