Message Transmission - Custom Messages
There are multiple possible methods to send messages through the Eval Kit:
GPS Pinger
Email Web App
USB-C
Telnet
The GPS Pinger feature will automatically queue messages containing
the Eval Kit’s GPS location, speed, solar input, battery charge level, and
more.
By default, the pinger is set to queue a message every 60 minutes. This
can be configured between 15-720 minutes, or disabled by the User (see
user command page).
This method does not require WiFi to be enabled.
When connected to the Eval Kit access point in Access Point (AP) mode,
the Email Web App can be accessed at the web address 192.168.4.1
Users can queue messages on the Eval Kit of up to 192 bytes using the
web App. When transmitted by the Kit, the message will be sent to the
specified “To: (email)” address.
This method requires WiFi to be enabled.
In Access Point (AP) Mode, users connect to the Eval Kit AP (default
name swarm-xxxx with password 12345678), and communicate to
address 192.168.4.1 to queue messages and send other commands.
In Station (STA) Mode, users specify the network to connect the Eval Kit
to, connect to that network on another device, and communicate with
the Kit using the new displayed IP address.
This method requires WiFi to be enabled.
Users can connect a USB-C cable from their device to the Eval Kit to
communicate over a serial connection.
To enable USB-C Data, the J7 SERIAL CTRL jumper (#2) must be
moved from FEATHER to USB.
Once connected, Users can queue messages and send commands
directly to the Swarm Tile in the Eval Kit.
The USB-C source will also charge the batteries in the Eval Kit.
This method does not require WiFi to be enabled. 8
