Hi
I am working on programming of esp32 connection with DWM1001. it would be appreciated if someone answer my clarifications below.
1- can a network including 6 anchors plus 1 gateway to tracking from 50 to 100 tag?
2- Is the computing of pos. done inside tag or anchors?
3- What is the main function for initiator?
4- Is the gateway connecting through ble with initiator or anchors or directly to tags?
4- How many anchors can be sending their data per one gateway?
Hi,
re: 1) Yes, that is possible. You just need to adapt the update rate of the Tags to not exceed the measurement capacity of 150 Hz per shared air-time area. E.g. 100 Tags at 1 Hz is no problem. 100 Tags at 2Hz would exceed the 150 Hz total measurement capacity and hence some Tags will not be able to achieve the 2 Hz update rate.
re: 2) The position is calculated inside the Tag.
re: 3) The Initiator is an Anchor that can start the network. I.e. it will start transmitting and allows other Anchors to join. Once running, the Initiator has the same functionality as a normal Anchor. The Initiator allows also to turn of the network. By disabling the Initiator, the devices will disconnect and stay passive until there is someone else who can start the network. There should only one Initiator in the network. There can be multiple Initiators as backup, but they should be in range with each others so they coordinate better on controlling timing of the network.
re: 4) The gateways communicates only via UWB with both Anchors / Tags. The BLE are used only for configuration and can be turned off if not needed.
re: 5) There is no specific limit of Anchors per Gateway. But if all the Anchors are in UWB range with each others, then the maximum number is 30 Anchors. This normally does not make sense, so when spread across the installation, there is virtually unlimited amount of Anchors possible. The same logic is for the Gateways. The Gateways are used only for data communication (uplink / downlink location and IoT data).
