In studio add the Thunderboard React under "My Products", select that and go to the Documentation tab.

As for your first question

I would like to know if it is feasible to use Bluetooth mesh and Direction finding at the same time

Technically it is possible but there would be tradeoffs and corner cases as well as potential negative impact on the Bluetooth Mesh network reliability. But in reality we don't have a software solution that combines these two things and also keep in mind that the direction finding software is not yet publicly available and you have to contact our sales to get your business case analyzed. Here is a link to get in touch with our sales team: https://www.silabs.com/about-us/contact-sales

Hi,

BG22 wil only have support for LPN nodes because of the limited RAM, and even that will only leave a few KB available for the application.

As for availability you need to get in touch with our sales, we don't discuss roadmap publicly on the forum: https://www.silabs.com/about-us/contact-sales

Hi,

Part EFR32BG22C112 is with 352KB FLASH , Is the BLE Stack inside Cortex M0 or it is in the Cortx M33?

The BLE stack is in flash. Cortex-M0 is reserved for radio related code, it can't be used by the application.

What is the size of the BLE 5.0 Stack?

Check this table from UG136. The size of soc-empty is pretty much the size of the stack as that has a very small application size that only advertises and reboots to OTA DFU mode when you write to the ota_control characteristic. Then on top of that you have the bootloader (size depends on how you configure it), apploader (for OTA), NVM3 and user data page. When you add all that together (and let's assume the bootloader is 24KB) you get 264KB which are required for the stack. The rest of the flash can be used for the application.

Can I download Mesh BLE Stack in this part ,if not why ?

No because the stack doesn't fit. Even for the BG22 part with 512KB of Flash you can only do LPN devices because there is only a few KB of RAM available for the application.

Hi,

In between that you still have Bluetooth 5.1 

You can check the SIG material on this topic:

• https://www.bluetooth.com/bluetooth-resources/bluetooth-core-specification-v5-1-feature-overview/
• https://www.bluetooth.com/bluetooth-resources/bluetooth-core-specification-version-5-2-feature-overview/

For any more in-depth information then you need to read the specification document.

2. Is there a possibility to see only my questions , sometime it is very convenient.

Actually if you go to your profile you are able to see your posts on the "Activities" tab.
