I'm not familiar with such issue and will try to check.

What version of CC3301 SDK are you using?

I was not able to reproduce. I'm getting the disconnection event every time.

are you sending data on the connection when the AP gets shut down? I was testing this with an idle connection.

I was testing with the FW of the latest plugin (0.7).

If I use My phone for AP, I can get the disconnection event every time when I close my AP. But for other wifi router, when I power off it, I can't get the disconnection event every time. when I did this test, I didn't send any data on the connection.

the fw I used comes from cc33xx_thickmac_package_0_4_0_1.exe, can you send me the latest fw for testing?

the wifi driver in cc33xx-mcu-plugin-0.7.zip is very different from the driver in cc33xx_thickmac_package_0_4_0_1.exe,

I saw the code of wpa_supplicant is included in cc33xx-mcu-plugin-0.7.zip, Is there any improvement in this version compared to the previous one?

should I upgrade my wifi driver?

The supplicant is not used by the 0.7 driver.

The driver is mostly the same with some bug fixes.

Updating the driver is required for using the latest FW.

The update is recommended as the new version will be closer to the (future) official one and it will enable us to support issue like this.

What is the supplicant used for?

Will the supplicant be used in next offical version?

When will the next official version be released?

the supplicant is the wi-fi connection manager (responsible connection to access point).

It will be used by future updates - not relevant for the current architecture of cc33xx (where it is implemented in the cc33xx firmware).

The next official drop is expected next month.

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
