Congratulations! I guess this wouldn't work to rejuventate my v3.0 module, though, because it has an older WROOM with fewer pins. -- Steve On Sat, 30 Jan 2021, Craig Leres wrote:
Success!
After protecting nearby components with kynar tape my hot air rework made "quick" work of removing the V1 module, including the ground pads on the back of the module. Then I hand soldered the new module in. (I wasn't sure if re-soldering the ground pads was important but I put a little solder paste on it and hit the back side of the board with a little hot air afterwards until the TPs flowed so there's some chance it's back to its original state.)
I repurposed an SMA/U.FL cable and wifi antenna from an old foxconn netbox and once I had flashed it and restore the config my wifi signal improved from -80.7 to -53.6 dBm. I'm pretty sure my (brick) chimney is inbetween my ruckus ap and this vehicle and had been thinking about relocating the ap but no need now.

It doesn't look like ovms knows there is extra memory?

Also when I was bootstrapping the old config a wifi scan listed my WPA3 ssid but the module couldn't associate with it. But I do see an option with newer versions of the idf:
https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/kc... CONFIG_ESP32_WIFI_ENABLE_WPA3_SAE
Select this option to allow the device to establish a WPA3-Personal connection with eligible AP's. PMF (Protected Management Frames) is a prerequisite feature for a WPA3 connection, it needs to be explicitly configured before attempting connection. Please refer to the Wi-Fi Driver API Guide for details.
I'm not sure if WPA3 requires V3 hardware or if it's purely an idf thing but it's something fun for the future.
