Not Getting ROLL value in SparkFun GPS-RTK Dead Reckoning pHAT for Raspberry Pi

[dcil123]

We Connected "SparkFun GPS-RTK Zed F9R Dead Reckoning pHAT for Raspberry

Pi" device to u-center v20.10 but we are not able to get ROLL

value also we connected to Raspberry pi4 run a python code to get Heading,

Pitch and Roll but here also we are not able to get the Roll value.

Note:

We rotated the device left and right, up and down to change the value of

Heading, Pitch and Roll.

Haven’t played with one of these before but did you calibrate it in a car first? Maybe roll doesn’t work until it’s been calibrated?
