Messages to EVERYONE (*)

Send directly from the serial console (two colons)

::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.

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

−−setssid WIFIssid
−−setpwd WIFIpassword
−−gateway on
−−gateway oe/dl (optional, default: OE)

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.
