|
|
This example configures the NEO-M8P-2 as a moving base.
|
|
It will output RTCM3 1077, 1087, 1230 and 4072.0 messages on UART1.
|
|
Connect UART1 TX to UART1 RX on a NEO-M8P rover. Also connect GND to GND.
|
|
The next example shows how to display the relative position of the rover.
|
|
|
|
Feel like supporting open source hardware?
|
|
Buy a board from SparkFun!
|
|
NEO-M8P RTK: https://www.sparkfun.com/products/15005
|
|
|
|
Hardware Connections:
|
|
Plug a Qwiic cable into the GNSS and a BlackBoard
|
|
If you don't have a platform with a Qwiic connection use the SparkFun Qwiic Breadboard Jumper (https://www.sparkfun.com/products/14425)
|
|
Connect UART1 TX to UART1 RX on a NEO-M8P rover. Also connect GND to GND.
|
|
Open the serial monitor at 115200 baud to see the output
