Hi @asadullah4571 

this might be due to some security on the phone or the board date/time not aligned (as there is no RTC battery on the board).

Regards.

[asadullah4571]

yes you are right, there is no RTC connection, 
but my IPhone hostpot is connected but i need to find the ip address but there is no ip found(IPV4), only i can see the IPV6, and why dhclient command not found. i have to do  manually add the ip address and default gatway.

and the second question why it is not connected automatic once i add the SSID and Password. only iphone is connected i tryied with Android but not connected

You mean using the iPhone as a "hotspot"?

Does this work with any other devices?

ie, as @PatrickF suggested, how do you know it's not just an issue with the iPhone?

[asadullah4571]

yes i am using iphone as a hotspot
No i tried many time with different different Android phone and also router but not connected i am facing this issue still now

Hi,

did you use this wiki page ?
https://wiki.st.com/stm32mpu/index.php?title=How_to_setup_a_WLAN_connection&sfr=stm32mpu

 

Did you removed any Ethernet cable on the board (might conflict).

Regards.

Hi, just tested on STM32MP157x-DK2 with the https://wiki.st.com/stm32mpu/wiki/How_to_setup_a_WLAN_connection#Automatic_WiFi_configuration_at_start_up

(only section 3 to be followed).

No issue to ping google.com (using Android phone as hotspot)

Tested after sync + reboot and also after a complete power down. No issue, connection is still automatic and working.

Did you have anything to share like above to see some error messages  ?

Is timedatectl show synchronized data/time ?

On my side, the "temporary failure  in name resolution" appear when I shutdown the wifi hotspot on the phone (so, you are likely not really connected to your iPhone hotspot).

 

Maybe start again the setup from a fresh Starter Package of Ecosystem v5.1.0
