Upgrade to 5GHZ

[thob]

hi, is there any potential upgrade path - on the hardware side - to provide 5GHz capabilities. The reason I'm asking is that my 2.4GHz WiFi is under ongoing deauth attacs from an unknown source, hence it's unusable for me.

Hi!
For a battery-powered display, it was because of reliable coverage and low energy consumption. The shorter range of 5 GHz makes it less attractive for that use case, and we’d need to test its impact on battery life. Your situation is a good example of where having the option could still be useful. The ESP32-C5 (we use the ESP32 C6-Mini) supports 5 GHz at the chip level, so it’s technically possible, but it is more expensive not available and doesn't support Zigbee.
Longer term, we’re more likely to explore Thread/Zigbee for its low-power design. It also operates at 2.4 GHz, but Wi-Fi deauthentication attacks wouldn’t directly affect it. It would require a Thread border router, and it wouldn’t avoid general interference in that band.

I'm aware of the shortcomings of 5GHz but also of those of 2.4GHz ;-/ Thread would be interesting but isn't the the amount of data it can handle an issue?
Aside from that, is there an alternative for me to get pics to the frame without wifi?

is this not accurate anymore https://www.espressif.com/en/news/ESP32-C5_Mass_Production?

Follow up regarding the ESP32 C6-Mini, does it support WPA3 and/or PMF/802.11w?

you can have a look into https://github.com/paperlesspaper/paperlesspaper-firmware-offline
it also offers a option to transfer single images via BLE. But especially for 13.3 inch display this is a slow process. Our hardware does not provide 5 Ghz functionallity.
We choose the C6 because of its modern low power optimized purpose. The C5 is more expensive and hard to become as a module.
