Hi,

We are running AM4378 with WL1837 interfaced over SDIO. We are running AP + Mesh solution.

Hi Ravi Kant,

Can you please let us know the test procedure used for reproducing the issues? Does the issue also happen with TI SDK? Also is this issue related to the https://e2e.ti.com/support/wireless-connectivity/other-wireless/f/667/p/963454/3559895#3559895

Hi Sudharshan,

This issue is happening when we are connecting 3-4 hotspot clients with TI devices in WPA2 Authentication mode. This is generally observed after running for 3-4 hours. After this we are not able to connect any more hotspot clients. Trying to connect any hotspot clients, we are not getting authentication responses from TI device.

This is being observed in both Our customized TI board & TI EVM.

This issue is observed with or without any mesh connection over mesh interface.

Hi Ravi kant,

We now have the R8.8 release (https://www.ti.com/tool/download/WILINK8-WIFI-NLCP available that integrates all the patches for known issues. Can you please try R8.8 and let us know if you still facing the issues.

Regards,

Hi Sudharshan,

I checked the release notes of the provided Release (R8.8).

In supported multi role modes, It doesn't include AP + Mesh Role. Is it supported & not mentioned?

We have some patches which you shared previously with us, some of the patches are missed in the listed patches in release documents. Are those patches already available in this release or we need to add them on top?

Most of the patches mentioned are already applied in out build. We are facing these issues with all those patches applied.

Hi Ravi kant,

R8.8 contains all the known issue fixes and patches (for both kernel and supplicant). It supports AP+MESH and is tested as part of the release. Also the FW is updated with few MESH use case fixes. We recommend to switch to R8.8 release.

Hi Sudharshan,

Thanks for the reply. We are using yocto build for creating image for TI. Can you provide some document or user guide which would help us in upgrading the yocto with this new release?

We are using AP mode (with WPA2-PSK) & Mesh Mode with SAE Security. Is it tested in this scenario or only Open Security?

We have obtained debug FW files from you in which you have fixes for Beacon loss & Recovery dumps. Are those fixes added in R8.8 release? or we need to use FW provided by you on top of R8.8 release?

Can you please point me to specific patch in the release notes which might have fix for this issue?

Hi Ravi Kant,

The same procedure should work for Yacto build as well. The standard TI release is based on TI SDK and the instructions are applicable to the same. The release can be ported to other systems like Yocto as well.

The testing is done with both open and secured mesh with the configuration mentioned above.
