The customer can not find the configuration/driver file for CC3351Bluetooth protocol in AM62 SDK.

Hi Fabio,

The Processor SDK 10.x does not include CC33xx BLE driver. BLE driver is a separate patch that is currently maintained in the CC33xx SDK and that is currently for kernel 6.1.

We have a GitHub repository where patches are maintained so that users can apply patches to the linux kernel and get the latest driver. We will be working on updating this soon for Processor SDK 10.

If customer wants to get evaluating the BLE now, they can use the CC33xx SDK as is for kernel 6.1.

Thanks! Could you share the guidance about how to configure and compile an image for burning NAND Flash？

Another question is that:

The customer is using AM62 SDK for Kernel 6.6.

Can AM62 SDK be compatible with CC33xx SDK as is for kernel 6.1?

Yes, you can use AM62x SDK 9.x because it uses kernel 6.1. So using this will not require additional patching.

If kernel 6.6 is required, as I mentioned above, please wait for me to post patches on to the GitHub Repo mentioned above. We will post patches for kernel 6.6 there.

Hi Sabeeh,

I use AM62x SDK 9.x to compatible with CC33xx SDK 1.0.7 and run it on AM62B-P1 start kit. When I run the WiFi sta_start.sh, I see a error: /usr/sbin/wpa_supplicant: No such file or directory.

I think it should make bluetooth to use UART interface and WiFi to use SDIO interface. Could you share the guidance about how to configure the SDIO and UART?

However, I could run the ble_enable.sh and the use bluetoothctl tool to scan bluetooth device. But it scan very slow although there are many bluetooth devices around. How to make it scan more quickly?

Another question about bluetooth connection. I use the connect command to connect the device I found, but I get a error that the device not available like the attachment.

I'm sure the device I want to connect is OK, because I could use APP LightBlue to conect the device.

Thanks.
