Hello, Just bought LD8001B ( https://hlktech.net/index.php?id=1214 ) but can not find the way to retreive information from that. Anyone has already succeed ? Under Linux, I use « CuteCom » to connect: nothing get out. Any other free software I should use ? Thanks.

HLK-LD8001B/H (and maybe all other radar sensor units from Hi-Link) are made all on ARM Cortex-M0+ microcontroller (chines version PY32F003F17U6TR of ARM32F003F6U6), they all are flashed with the same communication protocol and you can get it from other vendors that use same microcontroller with sam…

Hello all, first attempt did not work. I've used those connections: Arduino -> LD80001b GND -> GND 3.3.V -> VCC 5 -> RX 4 -> TX and LD80001b -> LD80001b P19 -> GND I tried also with LD80001…

[image] pozitroncho: ARM Cortex-M0+ microcontroller (chines version PY32F003F17U6TR of ARM32F003F6U6), According to datasheet, HLK-LD8001B is base on Cortez-M3 LD8001B is a radar sensing module developed based on ADT3102 chip, with monolithic integration of 76-81GHz RF transceiver system, …

[image] Patriboom: I've used those connections: Arduino -> LD80001b GND -> GND 3.3.V -> VCC 5 -> RX 4 -> TX If you use the code from #27, this connections are wrong. You need to connect TX (transmitter) from one side to RX(receiver) on another. So you MUST to swap a pins 5 and 4. I w…

Hello everyone, topic is still alive .... talking with HLink representative. Here are some important points : The device has a pair of pins named SCL / SDA but the device is not i2c compatible. We need a « UART TTL output device » to talk with the device FT232RL seems to not be a proper tool fo…

[image] Patriboom: FT232RL seems to not be a proper tool for that. Please provide a detailed description of what it was that lead you to that impression. [image] Patriboom: I have now a copy of the software shown in the user manual (pdf). It works well under Windows, but needs the approp…

[image] ptillisch: Please provide a detailed description of what it was that lead you to that impression. Hlink's tech said. [image] ptillisch: Have you tried using it with the UNO board configured as a UART TTL, as described in post #9 ? Yes I did. In fact. I'm surprised it did not …

[image] Patriboom: Yes I did. In fact. I'm surprised it did not work. Please provide a detailed description of what you mean by "did not work". [image] Patriboom: UNO 3.3 V <-> HLK 3.3V As I said five months ago: [image] ptillisch: I don't think that will work. From section 7 of…

There might be some confusion because we have discussed two different configurations in this topic. In post #9 , I describe the use of the UNO board as a simple USB to serial bridge to allow communication directly between a serial terminal running on the computer and the sensor. In that case, counte…

@ptillisch Thank for your clarification.

Please provide a detailed description of what it was that lead you to that impression.

Have you tried using it with the UNO board configured as a UART TTL, as described in post #9?
