If they're using the same Nordic BLE chips everybody else is, there's just gonna be a cap on how quickly you can move stuff, I think.

I've found the display capabilities of the current gen smartglasses pretty disappointing. Yes they're less obtrusive, but the resolution is pitiful. I've found the Vufine a lot more useful, if more ridiculous looking.

Mentra here.

The Nordic MCU they use isn't actually the limiting factor, rather it's the glasses' firmware. For bitmaps from third party apps (like AugmentOS), they enforce 194 byte chunk sizes and do not support RLE. Their first-party app does not have these limitations. We're stuck with this problem for the G1, but we're working with hardware partners to make sure future glasses don't have these issues.

If I were designing around this limit, I would put enough memory to be able to store a nice buffer of bitmaps in either direction and then do sends that don't change what's currently displayed. I feel like that memory probably exists, I just don't have access to the firmware sadly
