OSError: failed to init WINC1500 module

[Raj]

I have bought two WiFi Shields (Order # 3961) and two OpenMV Cam H7s (Order # 3955).
I am already in possession of two OpenMV Cam M7s

However, unfortunately, both the WiFi Shields are throwing the same error: "OSError: failed to init WINC1500 module" on all the 4 Cam Boards (two M7s and two H7s).

Steps followed:
Mounted WiFi Shield to OpenMV Cam Board
Powered the Board through USB
Tried both "connect_1.py" as well as "tcp_client_1.py".
Tried "Turn on WiFi Shield on Startup" in OpenMV Cam Settings.
Checked all connections thoroughly.

Kindly help, please.

How do you connect the shield ? A photo would help us a lot. And what firmware version do you have on those cameras ?

[Raj]

Will send a photo in a moment.
How do I check FW version, please?

[iabdalkader]

Bottom right corner of the IDE when you connect.

[Raj]

The FW is 3.4.1 - [latest]. Screenshot attached.
Photographs of one assembly are enclosed; i.e. H7+WiFi Shield

Hi, are the connectors on the camera soldered on?

[Raj]

Solved !!!

You are right. Thank you.
In the absence of soldering, the pins don't ensure proper/slug contact.

After soldering, now, at least one set is working (M7 + WiFi Sheild). Hopefully, the other WiFi Shield should also work and with H7 also.

Now... there is a new problem.
The Serial Terminal output remains at:
>>> Trying to connect... (may take a while)...
Running in Station mode...

Tried with:
"connect_1.py", "tcp_client_1.py" and dns_1.py

What can be the reason?

Please note when you solder the headers they should look like this:

[Raj]

Ya..
Done.
Thank you.

What is the problem ? It seems running normal. Did you set the SSID and KEY ? Do you have a mac filter or something like that blocking the camera ?

[Raj]

Yes. It is connecting to my Router. Please see enclosed image. No problem there.

Then, tried the following:
"connect_1.py", "tcp_client_1.py" and "dns_1.py"

But, the output of print(wlan.ifconfig()) is not showing up in the Serial terminal. It just displays the following and stays there:
>>> Trying to connect... (may take a while)...
Running in Station mode...

Never shows anything beyond that.

All the three scripts have "print(wlan.ifconfig())" - nothing shows up.
dns_1.py has "print(usocket.getaddrinfo("www.google.com", 80)[0][4])" - nothing shows up.
tcp_client_1.py has "print(client.recv(1024))" - nothing shows up.

Am I missing anything, please?

[Raj]

All the three scripts have the following 2 lines:

wlan = network.WINC()
wlan.connect(SSID, key=KEY, security=wlan.WPA_PSK)

When run, the above lines executes fine.
And that's it. Print statements that are there in the remaining portion of the code don't show up in the Termina of IDE

[iabdalkader]

Do you wait long enough for it to connect, get ip etc.. and print ?

[Raj]

Yes.
I wait for more than sufficient time... almost 10 minutes.

[Raj]

Working !!
Again, my fault.
Soldering was not good on some PINs, perhaps.
After re-soldering all PINs, it's working.

I am extremely sorry for the inconvenience caused.
Thanks for the patience and immediate responses.

I have also faced the same problem with my laptop. Every time I shut down my system, an update starts and the same thing happens during the time of starting up. I have searched a lot on the Internet for its fix, and finally, epson printer error code 0xf3 helped me a lot to solve the error.
