CC3235S: Delay when calling SlWifiConn_reset() API

JINHYEONG LEE

Part Number: CC3235S

Hi,

I'm using SDK 6.10, and I changed the project written in sl_* to SlNet* to use the OTA_IF module. (I'm referring to the mqtt_client example)

I'm use the WIFI_IF_reset() API(it called SlWiFiConn_reset() API) of the WiFi_IF module for the operation of restarting the network processor for network or WLAN setting (eg, DHCP or WLAN operation channel).

After the image is programmed, Reset API returns almost immediately, but after a certain situation (which happened when CC3235S is turned on for a long time), there is a delay of 2-3 seconds before returning.

If there is a delay, the same occurs even after rebooting the CC3235S.

I did not find this situation when calling sl_stop() and sl_start() in the existing project.

Attached file is the NWP log when Reset returns immediately and when delay occurs.

(In each log, the Reset operation was performed a total of 3 times.)

1222.NWPlog.zip

Please let me know why the delay is occurring and how to fix it.

Thansk.

Hello,

First, I'm not sure if there is a bug here as long as the NWP does get reset. However, there is a note in the documentation that the WIFI_IF_reset() should only be called when the WiFi connection is not active. So try disconnecting first and see if this speeds it up. Make sure your connection policy is also not set to auto, so you can manage the connection yourself.

Hi,

I checked that note too, and in all cases I called Wi-Fi_IF_reset() with no WiFiconnection active.
