"HJ-580XP" - A friendly introduction

A friendly introduction to "HJ-580XP" tiny BLE Module, resorces and example of use with Arduino Uno.

• Apart from its tiny 5*6.2mm size, this ble is also quite cheap but the best of all is that it runs on 2.5V - 3.7V and it has Ultra-low power consumption mode of 2uA - 11.5uA !!!

• Seems like to be one of the smallest BLE modules i've ever found out there on the Internet! and i feel amazing that i finally got it working after so many Issues and dificulties i came across, especially based on my experience with such so tiny electronics and my knowledge of electronics in general [...]

🤔 How to use it with Arduino UNO

Connections

• Based on the first image under:
  
  

  ARDUINO	BLE	Description	Pages
  GND	P06	Enables Uart RX Pin	d10, s6
  D11	P05/RX	Receives From D11	d10, s17
  D10	P04/TX	Transmits To D10	d10, s17
  D7	P00	Configuration Mode	d9, s7
  3.3V	3.3V	3.3V Source	d10
  GND	GND	Ground	d10

  
  
• _{^{This type of connection series, allows you not to have all, but most of the functionalities of BLE available.}}
• _{^{s stands for shoftware-manual and d for datasheet}}

Code Examples

Some examples to get you started, can be found under this repository i forked _{^{(in case of anything happening to the original one)}} which ended up helping me create my own example, under the folder examples here in this repository.

⚠️ Caution !!!

• ^{Make sure you have "HJ-580XP" and not "HJ-580LA" version.}
  • XP comes PREPROGRAMMED insted of LA which is not
  • In case you bought **LA** check this: video .
    
    
• ^{It is called "HJ-580XP" althought seems like it's called "HJ-580X" too.}
• ^{If P06 is not grounded for at least 5ms before sending data from arduino's D10 to P05/RX pin, the data won't be read from the BLE.}
• ^{As much as i can be aware, at least mine "HJ-580XP", doesn't look like the one on the seller's image which is what it suposed to seem based on my search (it should have been black and with a tiny cut and etc.), which makes me think if that is the "HJ-580LA" version but programmed by them? doesn't "really" matter as it is the same in dimensions and has only minor and not that important deferences [...]}
