Hi, Been trying to solve this for several days and no luck!
Attempting to communicate with BMP-388, Node Red debug returns
"Error: ENOENT: no such file or directory, open '/dev/i2c-1'"
Using node-red-contrib-i2c and for S&Gs tried node-red-contrib-bme280 with same results.
RasPi 4 with Docker 20.10.3
Node Red V1.2.7
NodeJS v14.15.4
nmp v7.5.1
Raspi-config i2c interface is on. Confirmed in /boot/config.txt
dtparam=i2c_arm=on
I can run all i2cdetect commands without sudo and returns expected results.
Created a BUS 4 i2c to test using:
dtoverlay=i2c-gpio,bus=4,i2c_gpio_delay_us=1,i2c_gpio_sda=23,i2c_gpio_scl=24
Same results not finding /dev/i2c-4
i2c-1 and -4 do exist in /dev and i2c-4 has 777 perms
htop shows "pi" as running node red.
Thanks for any help!
