I have been trying to connect the Seeediuno A1101 Vision AI Sensor to edge impulse, and when I try to collect data with it, I often run into this error. Do you know how to fix this. In addition, the Bouffalo Dev Cube to image the sensor is not on the downloads page listed in the setup instructions, so I am unable to image the A1101.
In order to get a proper working serial connection you should update the BL702 firmware. Links, howto and firmware can be found here: Seeed SenseCAP A1101 - Edge Impulse Documentation.
This worked, thank you!
