Pins of Wifi Shield is NOT able to directly plugged into Cam M7 ?

It looks like you redefined pins on Cam M7, but the Wifi Shield is too OLD?

  • pin sequence on cam M7:
    GND-VIN-P7-P8-P9-SYN-BOOT-RST
  • pin sequence on Wifi:
    GND-VCC-P7-P8-RST-BOOT-SWD-SWC

Any updated Wifi module?

I’m testing on my own wiring…

The upper pins on the wifi shield aren’t connected to anything so it doesn’t matter.

#3

Great to know that…

However, I still have an issue: How to test network?

I strictly followed https://docs.micropython.org/en/latest/esp8266/library/network.html#class-wlan, the code is:

import network
nic = network.Driver(...)

But, I failed to with the followingn ERROR message:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'Driver'

Does OpenMV be fully compatible with MicroPython?

Have you tried using our WiFi scripts under Examples → Wifi Shield?

Great !! Thank you !! It’s working NOW…

Is the IP address fixed to 192.168.0.8?

How can I set a static IP for OpenMV ?

#6

The IP address is given out by the DHCP server on your Network. If you use AP mode the IP will be static.

#7

That might happen. I’ve got 2 routers, both using the same SSID name.
The master one is a bit far, that is why I’m using the 2nd one as AP.
There is a possibility that OpenMV’s Wifi is ONLY able to find the 2nd router ??

#8

Hi, you should edit your routers config to assign the OpenMV Cam the same IP address based on the OpenMV Cam’s MAC address.

#9

I actually have already done that on my master(1st) router for OpenMV.
But, it seems that doesn’t help on the 2nd router (AP)…

Should I reboot both of my routers as well, because I’ve already reboot OpenMV multiple times, and it’s always assigned the IP: 192.168.0.8

The OpenMV Cam has no control over it’s IP address assignment. So, you have to go into your routers to make it static.
