Re: Can't get precise z Data.

Hello,

In the 'Stable “Z” for drone' chapter there are two submaps - beacons of the 'submap 2' are on the floor and used for X,Y location.
Beacons of the 'submap 1' reuse two beacons from the floor and use also two beacons on the wall, this submap is used for precize Z, even when drone is near floor.

Re: Retrieving distance from only one stationary beacon

Hello, Have you frozen a submap and map in dashboard? Until submap is frozen, system is in 'map build' state and hedgehog doesn't stream out location and raw distances. Even if you use only one stationary beacon. After freezing the submap/map with one stationary beacon you will get 1D tracking, so m...

Re: Should mm_get_devices_list work on a beacon? Or only on modem?

Hello, mm_get_devices_list should work only with modem, beacons don't know list of the devices. API is mostly intended for work with modem, not with beacons. For reading streaming data from mobile beacons you can use another library: https://github.com/MarvelmindRobotics/marvelmind.c In future updat...

Re: Having problem to get "3D Fix" using the marvelmind's "Starter Set NIA-SmallDrone" with a paired super-beacon

Hello, For using paired beacons with PX4 you will need to update to latest version of software (6.240) and purchase a license for UBX (U-Blox) protocol support: https://marvelmind.com/product/mmsw0003/ With this license you will be able to enable UBX protocol output from mobile beacon, which is requ...

Re: I have connected the GPS to the drone. NO GPS is displayed. How do I fix it?

Hello, There are two configurations with different settings and protocol of data transmission: 1. Configuration with using Marvelmind protocol - recommended by Ardupilot team: https://ardupilot.org/copter/docs/common-marvelmind.html 2. Configuration with NMEA0183 protocol - tested in Marvelmind: htt...

Re: Lost tracking data near one beacon

Hello, As I see on the screenshot, beacon 4 has only RX1 sensor enabled when map is frozen. Try to enable all sensors, or at least RX4. You should disable only unuseful sensors, which are oriented outside of tracking area, for example directly into wall or ceiling. Check sensors enablng for all stat...

Re: Cant turn any beacons to hedgehog

Hello,

As I see on the screenshot, your beacon is uploaded by IA firmware.
Beacon HW4.9 can't be hedgehog in IA, because it doesn't have multi-frequency ultrasonic receiver (microphone).
This type of beacon can be hedgehog only in NIA or MF NIA (when it doesn't receive, but only emits ultrasound).

Re: Controlling a robot with a coordinate inputed by python.

Hello, You can find protocol of sending waypoints to a robot here (see section 8.1): https://marvelmind.com/pics/modem_usb_protocol.pdf Each data packet of this format spicifies one waypoint, so you should send a sequence of this format to the modem. Also you can find protocol of sending waypoints d...

Re: Communication between IMU paired beacon and Arduino

Hello, The angle should be sent by the same way if you enable 'IMU fusion for angle' What do you mean by 'hedgehog stops send the angle' - the angle is always zero or packets with coordinates were not received at all? Did you get good tracking of paired Super-Beacons in dashboard? Please send us the...

Re: Longitude in NMEA output

Hello,

What hardware type of beacons do you use (HW4.9, Super-Beacons or others)?
Can you share some example with wrong result:
- location in dashboard (X, Y)
- location from NMEA sentense (latitude, longitude)
- geo reference (latitude, longitude)
We will check the data and reply.
