The Wisnode Lora is a RAK811 development board with a arduino form factor. The default firmware has a convenient AT Command set for quick startup.

Included:

1 x Wisnode dev board
1 x 915MHz antenna

This board can be used in three ways (see jumper configurations below):

1. Direct connection through USB port (no arduino required - used for initial testing and setup)
2. As Arduino Shield: the RAK 811 module connects to the arduino through pins D0 and D1.
3. As a programmer for the onboard RAK811 module.

Direct Connection jumpers (default baud rate 115200)

This jumper position connects the onboard USB directly to the RAK811 module.
Apart from the circled jumpers, make sure that BOOT is connected to GND.

Use the following command to change the baud rate to 9600, 8, N, 1: at+uart=9600,8,0,0,0

Arduino Shield Jumpers (default baud rate 115200)

This jumper position connects Arduino pins D0 and D1 directly to the TX and RX of the RAK811 module.
Apart from the circled jumpers, make sure that BOOT is connected to GND.

Note that the jumpers must be disconnected when uploading sketches to the arduino.

In order for this board to work reliably with the arduino the baud rate must be reduced.
Use the following command to change the baud rate to 9600, 8, N, 1: at+uart=9600,8,0,0,0
