It says 512MB here: GL-S1300 / Convexa-S - GL.iNet
and 256MB here: Amazon.de
It’s 512MB ram, like here:
Seems like the official store for Amazon DE has copy pasted the B1300 info incorrectly.
The Q&A also says it doesn’t have BLE. Very confusing.
Is there a convexa with 512MB without BLE/Zigbee but that supports USB Zigbee?
Prefer to use Zigbee USB with UI and confirmed device support
