Hi, I am using the Grove Vision v2 connected to an Arduino Nano esp32 (Alvik Robot) using a Grove connector. But I have some issues, when I run a scan, it works:
Scan i2c bus…
i2c devices found: 3
Decimal address: 40 | Hexa address: 0x28
Decimal address: 43 | Hexa address: 0x2b
Decimal address: 98 | Hexa address: 0x62
It’s detecting the Grove Vision in the address 0x62, but when I try to READ or WRITE I am getting [Errno 116] ETIMEDOUT or [Errno 19] ENODEV. To start working, I need to press the white and black button (white first and black later) several times to enable bootloader mode (Grove Vision AI Module V2 | Seeed Studio Wiki). After multiple times (it’s random) the Grove starts answering:
buffer: bytearray(b’\r{“type”: 1, “name”: “INIT@SENSOR”, “code”: 0, “data”: {“sensor”: {“id”: 1, “type”: 1, “state”: 1, “opt_id”: 0, “opt_detail”: “240x240 Auto”}}}\n’)
I am getting this error with Micropython (Arduino Nano ESP32). Also I tried the official Seeed_Arduino_SSCMA.cpp (in a Cytron Maker Nano RP2040) and got the timeouts too.
In both cases I am connecting the Grove vision using the grove port (I2C), Is it normal? Do I have a failed Grove Vision V2?
If I connect the Grove Vision V2 kit using an USB connection to Ubuntu with Minicom, it works flawlessly. I throw commands (serial) and the Grove Vision v2 answer inmediately, I don’t need to reset it:
Welcome to minicom 2.9
OPTIONS: I18n
Port /dev/ttyACM0, 16:47:12
Press CTRL-A Z for help on special keys
{“type”: 0, “name”: “NAME?”, “code”: 0, “data”: “Grove Vision AI V2”}
{“type”: 0, “name”: “MODEL”, “code”: 0, “data”: {“model”: {“id”: 1, “type”: 0, }
{“type”: 0, “name”: “INVOKE”, “code”: 0, “data”: {“model”: {“id”: 1, “type”: 0,}
{“type”: 1, “name”: “INVOKE”, “code”: 0, “data”: {“count”: 1, “perf”: [7, 50, 0}
Tried a lot of things, reset the I2C bus, add waits between calls, everything failed.
Don’t know if someone else is using the Grove Vision v2 with the grove port, if you do it, Can you tell me your experience?
Thanks!
