        We import latest SDK version 2.14.0 ,In that we face limited channel wifi Scan list issue. While we scan for available wifi network , we only get available ssid within (1 to 6 channels for 2.4GHz and 36 to 144 channel for 5GHz ) ,if my wifi network is available in 8 th channel for 2.4GHz and 161st channel for 5GHz i can't get it in Scan list. Both AP mode and station mode same issue happen.

In SDK version 2.11.1 we don't face this limited channel wifi Scan list issue.

Can you kindly let us know is there is any configuration changes needed to Scan all channel wifi network in latest SDK version 2.14.0 , I attach scan list log for both 2.11.1 and 2.14.0 SDK versions.

Hello,

Thank you, while I investigate the SDK 2.14 information can you please help me by performing a test with the 2.13. version.

Hi keerthi,

         We are using MAYA W166 with IMXRT1064 ,using their SDK application for modem communication.We try SDK version 2.14.0 as suggested.In that latest SDK we are face iPhone pairing issue,So that we revert back to SDK version 2.11.1.Where WiFi connection is flaky with configured SSID.I attach log for your reference.

When Device unable to connect with network we receive following callback,

2023-08-23 21:03:26.428000 -------- wlan_event_callback 1 --------

2023-08-23 21:03:32.507000 -------- wlan_event_callback 5 --------

Finding : In first level debugging we found configured ssid was available in scan list at not connecting case.

We need clarification on following points:

• We need fix on wifi connection flakiness for cannot connect to Wi-Fi  issue case.
• As suggest ,we try to move related file from SDK version 2.14.0 to SDK version 2.11.1, but we don't know what are Specific files need to move and it will supported on current build tool environment (MCUXpresso IDE v11.6.1_8255) what we currently using.

Please help us to fix this issue as soon as possible.

Hello,

We understand the current troubles that you are facing, the recommended software is the SDK version 2.13 instead of the 2.14. Please help me using this.

We have noticed some troubles, also we recommend to use the MCUXpresso latest version 11.8.

          We are working with wifi modem(MAYA W166 and IMXRT1064) and using a SDK version (2.14.0) for modem communication. We are experiencing difficulties with device-to-mobile(iphone) pairing, particularly in Access Point mode.        

Where we are not facing AP mode connection issue, in SDK version 2.11.1.

Please support to resolve this issue as soon as possible.

[nxf77486]

Hello,

We have notice some details on the latest SDK version, we were able to reproduce the AP connection to a mobile phone(iphone) with no troubles with the SDK version 2.13.0. Please help me by confirming that this is also working for you.

[nxf77486]

Hello,

Thank you in advance for contacting NXP support.

Can you please help me by confirming some extra details in order to find a solution to your case:

• What is the SDK version being use, if it is not the more recent one please use the more recent version.
• Just to confirm you are using the wifi_cli example with the STA configuration and connecting your laptop as an AP?

Also please help me reviewing the following documents:

UM11441-Getting-Started-with-NXP-based-Wireless-Modules-and-i.MX-RT-Platform-Running-on-RTOS

• This document contain hardware use information on the section 4.2.4.1 for the usage of the EVK-MAYA-W1

UM11442-NXP-Wi-Fi-and-Bluetooth-Demo-Applications-for-i.MX-RT-platforms-User-Guide

• In this document on table 4 Macros for Wi-Fi you will find the note for the usage of the latest SDK version 2.14.0.

This documents are located on the SDK->docs->wireles folder.

Please let me know if there is anything else where I can help you.

Here i mentioned the wifi low signal connection issue details.

      We are using MAYA W166 with IMXRT1064 ,using their SDK application for modem communication. Where we are facing wifi connection issue when the signal strength is -60dbm and above, even though router is available in scan list. SDK 2.11.1 version.

   We carried out low signal related test cases in both 2.4GHz and 5GHz band.

• In 5GHz band, the device is unable to connect and communicate with the server at -84 dbm it is flaky and take more then 46 sec.
• In 2.4 GHz the device is unable to connect at -60 dbm signal strength. SDK 2.11.1 version.

       For connection test at low signal we config device with wifi router and kept device 6 to 10 meter away from router. with this test setup ,device shows (-60 dbm to -80dbm)signal strength.

     In this wifi signal strength range we face below issues

• Device not connect with network within 30 seconds. (-60dbm to -75 dbm)at 2.4Ghz and (-75dbm to -85dbm) at 5Ghz

Some times device able to connect with router but unable to transmit data to server over TCP protocol.With (-60dbm to -75 dbm)at 2.4Ghz and (-75dbm to -85dbm) at 5Ghz try to send sample data to server via TCP protocol this will reproduce the issue what we currently facing

Hello,

I understand the concern and the troubles you are currently facing, but in this case what we highly recommend is to use a more recent SDK version in this case what we are currently recommending to our clients is version 2.13. The SDK version you are using is a downgrade version that has been optimized on this 2.12 version.

Dear Sir,

Following your suggestion, we imported SDK version 2.13.0 and tested the Wi-Fi/Webconfig example program. However, we encountered a limitation with the Wi-Fi scan list. When scanning for available Wi-Fi networks, we can only retrieve a list of 10 SSIDs. Furthermore, there is no support for the WPA3_SAE security type, which is a requirement for our application.

With SDK version 2.11.1, we did not face the limited channel Wi-Fi scan list issue.

Due to these issues, we are unable to integrate the recommended 2.13.0 SDK version into our project.

I attach a tested log for your reference.

Hi,

Could you please share with me all the terminal output from your test? I’d like to see both commands and outputs.

What do you mean with WPA3 support? I was able to connect to a WPA3 AP. What kind of problem do you get?

Is there another problem beside the number of scanned networks in SDK 2.13.0?

Regards,

Daniel.
