BLE Beacon scanning

Hello,
You need a HM-1x bluetooth module(http://wiki.seeedstudio.com/Bluetooth_V ... LE_Module/),
and write the program by yourself.
I guess this page may help: https://forum.arduino.cc/index.php?topic=288624.0

Re: Problem with UART WiFi v2 MQTT

Hello,
the grove UART WiFi v2 is used for simplifying your code, so the problem is that this module is not programmable, if you want to use the library of ESP8266, why not use stuff like nodemcu directly?

Re: Can I include both IR Emitter & IR Receiver in 1 board?

Hello, the demo of seeed wiki used them on two board, so if you want to install both of them on one board, you need to write code yourself. And The problem is that readDigitalPin()only read the high/low of the pin, and the IR Emitter&Recivers translate a data package a time, I do not suggest you com...

Re: Using multiple Grove I2C V1.3 Motor Drivers

Hello,
the problem is that there is no delay function in your code. So you set up the motor1, stop the motor2, set up the motor2, stop the motor1……you just do all the things at almost the same time, so it seems that they work together.

Re: Analyze with CAN-BUS Shield V2

Hello,
Congratulation! you have received so many information means that your hardware works well and received right data. But I have nothing to do with the data received too. If I was you, I would contact the technical support of Peugeot for documents.
Good luck!

Re: Sound Sensor - Value keeps rising over time

Hello, It looks that there is no problem with your code. I suggest you test the official example of the sound sensor to see if the phenomenon still happens. Then you can find if there is a problem with your hardware. Your experiment lasted half an hour, so although the ambient noise has changed, it ...

Re: CAN BUS OBD2 4 Byte messages

Hello,
I want to know why do you define an 8-sized array with 7 elements?

Code: Select all

unsigned char s0pid020[8] = {4, 65, 00, 24, 59, 80, 00}

Re: Sound Sensor dB range

Hello,
This grove is designed for voice control, but not measurement. And the output of the example code is a relative value. So if you want to use it to measure accurate volume, you need to establish the mathematical model and calculate the range by yourself.
