  • ifconfig: to get device network interface configuration info if station is enabled and connected to an AP

  • net scan: to do a WiFi scan and get available AP nearby.

  • net on: to enable STA interface

  • net off: to disable STA interface

  • net config: to configure and connect to an AP, must provide essid and password (see -wp)

  • net status: to get STA state. It returns True if enabled, False if disabled

  • ap status: AP state ; returns True if enabled, False if disabled

  • ap config: AP configuration of essid and password with authmode WPA/WPA2/PSK, (see -ap), needs first that the AP is enabled (do $ upydev ap_on)

  • ap scan: scan devices connected to AP; returns number of devices and mac address

  • i2c config: to configure the i2c pins (see -i2c, defaults are SCL=22, SDA=23)

  • i2c scan: to scan i2c devices (must config i2c pins first)

  • set rtc localtime: to pass host localtime and set upy device rtc

  • set rtc ntptime: to set rtc from server, (see -utc for time zone)

  • datetime: to get date and time (must be set first, see above commands)

  • set hostname: to set hostname of the device for dhcp service (needs wpa_supplicant.py)

  • set localname: to set localname of the device for ble gap/advertising name (needs ble_uart_peripheral.py)

  • shasum -c: to check shasum file

  • shasum: to compute hash SHA-256 of a device file

  • sd: commands to manage an sd

  • diff: use git diff between device’s [~file/s] and local file/s

  • enable_sh: upload required files so shell is fully operational

  • uconfig: set or check config (from _config.py files in device)

  • uptime: shows how long the device has been running (requires uptime.py)

  • cycles: shows how many times the device has been rebooted (requires cycles.py)

  • load: run one or more local scripts in device. (accepts “*” wildcard and brace expansions)

  • sd auto: experimental command, needs a sd module with sd detection pin. Enable an Interrupt with the sd detection pin, so it mounts the sd when is detected, and unmount the sd card when it is extracted.

Note

These commands needs sdcard.py in the device, see upyutils directory in upydev github repo. sd_auto also needs SD_AM.py in the device.
