  Intro

  Hey, what's up, Guys! Akarsh here from CETech.

  This project of mine is more of a learning curve to understand the working of the small Bluetooth module from Reyax.

  First, we will understand the module alone and try to use it directly, then we will connect it to an ESP8266 and make a simple LED control project.

  At the end of the tutorial, we will be able to use the RYB080l module standalone and with micro like esp8266.

  Let's start with the fun now

  Parts

  The Bluetooth modules I have used are from Reyax.

  Firstly the main Bluetooth module is RYB080l HERE.

  We use the breakout module of the Bluetooth module which is called lite version which you can find HERE.

  Finally, we use an ESP8266 module from DFRobot which you can buy from HERE.

  I would also recommend to get your PCB manufactured. You can order your PCBs from PCBWAY as they offer 10 PCBs for just $5. Check out their online Gerber viewer function. With reward points you can get free stuff from their gift shop.

  Taking a look at the module and its datasheet

  The features of the module:

  • Bluetooth v4.2 & v5.0 with Bluetooth Low Energy

  • TI CC2640R2F ARM® Cortex®-M3 industry-standard chip

  • Can connect two Bluetooth devices at the same time

  • Support Host-Client role.

  • Designed with PCB integrated antenna, Suitable for SMD. Size: 115.94mm^2

  • Metal cover against EMI interference

  • Transmitting, Receiving, Wake-up by only 2 UART pins

  • Control easily by AT commands

  We see the following detail:
