HOW TO REDUCE WIFI CONNECTION TIME

[KAVASKAR s]

Hii, I'm using the ble_coex sample.
My process involves connecting to WiFi, transmitting some data via HTTP, and then disconnecting from WiFi.
This operation typically takes around 5 to 5.5 seconds. However, when solely connecting to the WiFi access point, it takes only 4 to 4.5 seconds.
Is this flow to be expected, or is there a method to decrease the time it takes to connect to the WiFi access point?

thanks.

Hi,

Hii, I'm using the ble_coex sample.

Have you tested the same times without BLE coex?

Apologies for my late response. I experimented with both the WiFi provisioner sample and the WiFi station sample, and it took approximately 4.5 to 5 seconds to connect to WiFi. Additionally, when I tried the WiFi scan sample, it took about 4 to 4.5 seconds to scan all the WiFi devices. Could you tell me the typical time it should take to connect to a WiFi device?

I tested the WiFi station sample using the nRF52840 DK with the nRF7002EK, and it consumed nearly 99% of the RAM. How can I reduce this memory usage?

[Sigurd Hellesvik]

Yes, that is expected time for a scan.

Hii, I'm entering WiFi credentials like the SSID and password, but I've noticed it takes about 4.5 to 5 seconds to reconnect to a previously used WiFi access point. Why is there such a delay, considering I have already added this network? is it expected behavior

[Sigurd Hellesvik]

It will still scan for the AP in question, to resolve BSSID etc (the MAC address of the AP).

Think of the scenario where you have a wifi-mesh setup at home, there's 3 APs with the same SSID (ie. human readable name) and WPA PSK. It'll still need to get the BSSID (unique MAC of the APs) to know which one it should connect to.

I've inputted the Wi-Fi credentials, such as the SSID, password, and BSSID. The process took about 4.5 to 5 seconds. Also, is there a way to decrease the time it takes for a station to connect to an AP station?

[Sigurd Hellesvik]

No, "wifi connect" will internally do a scan internally
