MDEK1001 display 3-exes acceleration and position at the same time

Hi Thai,

there have been a couple of posts related with this topic:

Read accelerometer from API

The firmware guide walks through how to read the position (presumably relative to a spatial arrangement of DW1000 chips all distance-ranging or otherwise self-locating relative to one another, I’m just assuming). Oddly, I just get 4 0s back for x,y,z, and qf, no meaningful data. Perhaps someone has some thoughts on that, although it isn’t my primary question here. In shell mode, I can run “av” to get back accelerometer values and these seem to actually contain meaningful data, as they indicate …

Sending Accelerometer data, and data from other sensors through MQTT

Hi, I’m using the PANS 2 firmware and gateway to get position from tags and it worked fine. But, the idea is get other information from tags, like accelerometer. I’d like to include other sensors as well (buttons, gas sensor) and include some actuators like buzzer and so on. Is it possible read accelerometer data generated by the built-in sensor through MQTT? Is it possible access GPIOs available on the board, reading and writing them through MQTT? (I’d like to install custom buttons, and ac…

In general you can write an user application using DWM library. In the application you need to configure the module to not use the stationary detection and then using the I2C interface you can access the accelerometer. See the DWM1001 Firmware API documentation https://www.decawave.com/dwm1001/api/
