Beacon disappear without enabling the Hedgelhog mode

[greenworld]

Hi everyone,
I bought a set includes one modem, and five beacons (HW4.9 - 915Mhz/31.6kHz).
I have already flashed the latest firmware for all modules.
However, there is one module not appear when I wake it up. (another one are fine)
Also in the table, the data for this module is yellow highlighted and lacks one data column.
Please kindly see the video (https://drive.google.com/file/d/1u5jDNs ... sp=sharing)
and give me some suggestion to solve it.
Thank you very much.

Hello,

1. As I see on your video all beacons are visible and shown on the map. But when you are switching mobile beacon 5 to stationary, it disappears from table of distances, because only 4 stationary beacons can be in one submap. If you need more stationary beacons, you should add more submaps.

2. All your beacons are 31 kHz, but two of them are adjusted to 25 kHz - beacon n5 and beacon n2. You should set 'Ultrasonic frequency' for them to 31000 Hz or similar value specified on the sticker on the bottom of the beacon. HW4.9 beacon can normally emit and receive only its own ultrasonic frequency, so 'Ultrasonic frequency' should be same as on the sticker or nominal value (31000 Hz for your case).

For the comment 1, I followed this video: https://www.youtube.com/watch?v=sOce7B2_6Sk. They showed that five stationary beacons can be in one submap. Aslo, the table includes five columns and rows data for five beacons. But it cannot be observed like that in my situation.
Please take a look and help me to explain!
Thank you!

Hello greenworld,

In the video you can see an old version of SW, and it had ability to add more than 4 stationary beacons per submap.
So now, in the latest SW, it is limited with 4 stationary per 1 submap.

Thanks for your information.
For the comment 2, all of my beacons are 915Mhz, not 31.6kHz. May I know, how could you know that "but two of them are adjusted to 25 kHz - beacon n5 and beacon n2" ?
I checked the performance and I get unprecise response, can you please instruct me how to improve the accuracy and reduce the latency?

Hello again,

Please, do not confuse the frequency of radio to and the frequency of ultrasound.

- Correct, radio frequency - 915MHz for your set

- Ultrasonic frequency have to be 31kHz for all your beacons. You should set 'Ultrasonic frequency' for beacon 2 and beacon 5 to 31000 Hz or similar value specified on the sticker on the bottom of the beacon. HW4.9 beacon can normally emit and receive only its own ultrasonic frequency, so 'Ultrasonic frequency' should be same as on the sticker or nominal value (31000 Hz for your case). 31.6kHz rounds to 31kHz.

All of your beacons must use an ultrasonic frequency of 31kHz. Beacon 2 and 5 both need to have their 'Ultrasonic frequency' set to 31000 Hz, or whatever value is written on the label at the bottom of the beacon. Your HW4.9 beacon's 'Ultrasonic frequency' should match the value specified on the label or the nominal value (31000 Hz in your case) since it can only transmit and receive its own ultrasonic frequency. The frequency of 31.6kHz is rounded down to 31kHz.
