@PJ_Glasso I need help with one aspect of working with the UART communication to the Grove Vision AI V2. The model (a pre-trained model such as the “Gesture Dection” or “Face Detection” or “Person Detection–Swift YOLO” is not loading into RAM upon power up or reset of the WE2 it seems.
This can be shown using PUTTY and a USB to Serial adapter connected to the Tx/Rx pins of the WE2. When I connect to the WE2 via PUTTY and issue an AT+RST\r command it replies:
{“type”: 0, “name”: “INIT@STAT?”, “code”: 0, “data”: {“boot_count”: 61, “is_ready”: 1}}
Which seems to imply the WE2 is ready.
When I then issue an AT+MODEL?\r command via PUTTY to the WE2, it replies as if no model is present or at least not ready in RAM (as “Size”:0).
{“type”: 0, “name”: “MODEL?”, “code”: 0, “data”: {“id”: 1, “type”: 0, “address”: 4194304, “size”: 0}}
Reconnecting the WE2 via USB to SenseCraft Workspace shows the model actually still is present and working.
Is some communication other than an AT command via the UART Tx/Rx of the WE2 necessary to initialize the model?
Or is there some critical timing issue I’m not accounting for?
Or is the I2C connection to the WE2 needed?
Or is the USB connection needed by the WE2 SSCMA_Micro firmware?
The WE2 device version is 2025.01.02.
I’m not finding additional troubleshooting avenues to pursue at the moment in any provided documentation or GitHub files.
