"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 [...]
