Commands directly from the smartphone APP:

GATEWAY, GPS, BUTTON, TRACK BME, BMP

Weather data query, if a BME or BMP chip has been connected to the I2C bus, can be called with the following command in the APP:

WX-Info

Position data, if a GPS chip is present on the hardware, can be called with the following command in the APP:

POS info

❌ these commands are prepared only for input in a serial console connected to the node. Note: not intended for input via APP.

--help query the list of commands
--info query the current operating parameters
--mheard (- - mh) display the stations listened to via LoRa-RX since the last reboot
❌ --setcall Setcallsign (only valid calls according to APRS) (auto reboot after 15 seconds)

❌ --setssid SetWIFIssid (auto. reboot after 15 seconds if ssid and pwd are set)
❌ --setpwd SetWIFIpassword (Auto. reboot after 15 seconds if ssid and pwd are set)
❌ --setwifiapon/off Set WEB service in access point mode
--sethamnet use the HAMNET IP for the MeshCom server connection (auto. reboot after 10 seconds)
--setinet use the INTERNET IP for the MeshCom server connection (auto reboot after 10 seconds)
❌ --gatewayon start Gateway to the MeshCom server via WIFI/ETH-connect

Send messages to ALL - directly from the serial console

:textnachricht eingeben und <ENTER>

It is also possible to send several prepared commands at once. It is best to prepare them in a notepad or similar and copy them into the buffer with CTRL+C and then paste them into the serial console connected to the MeshCom node with CTRL+V.

Messages in direct mode (DM) - send directly from the serial console

If the MeshCom node is to be used as a gateway, the following additional commands are required:

--setssid WIFIssid
--setpwd WIFIpassword
--gateway on

The gateway automatically configures the IP address of the MeshCom server based on the local IP address obtained via DHCP. To fix the MeshCom server selection when the local IP address is assigned via NAT, the desired MeshCom server IP address can be set to fixed.
