introduction to rn4020, rn4020 pinout,rn4020 working, rn4020 features, rn4020 applications, rn4020Hello friends, I hope you all are doing great. In today’s tutorial, we are gonna have a look at detailed Introduction to RN4020. RN4020 is a completely licensed Bluetooth category 4.1 low energy consuming unit. This module is surfaced with the Bluetooth which is organized by Unpretentious ASCII instructions by UART interfacing. It also comprises all Bluetooth SIG sketches and (MLDP) Microchip low Energy data for customized data.

The scripted features can be secondhand to allow unconnected process without any Microcontroller or mainframe computer. It can be controlled from a distant position by other modules with the protected assembly and it can be reorganized by means of UART interfacing or by air. In today’s post, we will have a look at its casing, pins, structure, applications, etc. I will also share some links where I have interfaced it with other microcontrollers. You can also get further information about it in comments, I will guide you further about it. So, let’s get started with a basic Introduction to RN4020.

Introduction to RN4020

  • RN4020 is a completely licensed Bluetooth category 4.1 low energy consuming unit. This module is surfaced with the Bluetooth which is organized by Unpretentious ASCII instructions by UART interfacing.
  • This unit incorporates RF, a base-band regulator, and an API (application program interface) processor, which makes it a low energy user Bluetooth module.
  • It has an inherent high-performance PCB antenna which is modified for elongated assortment, normally over 100 meters distance.
  • Its compressed dimensions allow the comfort of incorporation in size- controlled applications. It is used in any less expensive microcontroller for intellectual Bluetooth low energy consuming applications.
  • For unpretentious sensor use, its interior scripting abilities allow straightforward functions to be applied without the need for exterior host Microcontrollers or software development tools.
  • It provisions 13 communal sketches and 18 communal amenities, which are implemented by Bluetooth Special Interest Group (SIG). For all sustained contours and facilities, RN4020 could be organized to act as waitperson and customer roles at the equivalent period.
  • Besides, RN4020 provisions Microchip sequestered contour Microchip Low Power Data Profile (MLDP) that put on Serial Port Profile (SPP), which is well-defined in Bluetooth Definitive and allows data tributary between two expedients.introduction to rn4020, rn4020 pinout,rn4020 working, rn4020 features, rn4020 applications, rn4020




Pinout of RN4020

  • These are the main pinout of RN4020 which are described below.
    Pin#TypeParameters
    Pin#1GNDIt is ground pinout.
    Pin#2AIO2It is analog programmable bi directional input output pinout.
    Pin#3AIO1It is analog programmable bi directional input output pinout.
    Pin#4AIO0It is analog programmable bi directional input output pinout.
    Pin#5UART TXIt is a UART Transmitter (TX) pinout.
    Pin#6UART RXIt is a UART Receiver (RX) pin.
    Pin#7WAKE_SWIt is bottomless Snooze Awaken when it becomes active it rouse module from Unfathomable Snooze.
    Pin#8CMD/MLDPIt works in command and MLDP mode, in command mode, UART data send to the command translator. During the MLDP method, UART data is sent to MLDP Bluetooth UART LED contacts.
    Pin#9GNDIt is a ground pin.
    Pin#10CONNECTION
    LED
    PIO[1]
    SCK
    PWM1
    It is an evasion condition output.

    When it is in the energetic condition it shows that the device is linked with the distant expedient. When it is not energetic it displays there is no association with another expedient.

    Pin#11MLDP_EV
    PIO[2]
    CS
    PWM2
    It is for MLDP data indication. If it is in the high state which means that data has acknowledged, in a low state, there is no data.
    Pin#12WS
    PIO[3]
    MOSI
    PWM3
    It is output for movement indication. If it in energetic state component is working properly if not the device is not working.
    Pin#13PIO[4]
    MISO
    It is MISO for Diagnostics and Workshop Regulation if a pin 17 avowed.
    Pin#14CTS
    PIO[5]
    It is earmarked for CTS if hardware movement controller is permitted on the UART.
    Pin#15WAKE_HWIt is hardware wakeup from the latent condition. Set the Pin (15) high state to module eliminates from the inactive condition.
    Pin#16 GND It is a ground pin.
    Pin#17SPI/PIOSPI/PIO for pinouts 10-13, active.
    Pin#18RTS
    PIO[6]
    It Earmarked for RTS if hardware movement controller on UART is empowered. If the data communication to RN4020 requisite is stopped, declare RTS to high. RTS pin functions self-sufficiently from the CTS (pin 14).
    Pin#19PWM4
    PIO[7]
    It is a standby PIO.
    Pin#20RSVDIt is DMOS comprehensive Bridge 2 Yield A pin
    Pin#21SDAIt is SDA Statistics contour of the I2C interfacing. The RN4020 constantly performances as the I2C Dominant.
    Pin#22SCLIt is I2C Clock.
    Pin#23VDDIt is a power supply.
    Pin#24GNDIt is ground pinout.

Features of RN4020

  • These are some features of RN4020.
    • It is entirely specialized Bluetooth form 4.1 component.
    • It is on-panel Bluetooth Squat Energy 4.1 heap.
    • On this module, ASCII expertise interfaced API over UART.
    • This module has DFU above UART or Above the air.
    • For sequential transmission of data, it has MLDP.
    • This module sends and receive data to distant areas and can control them.
    • It hs 64 KB interior flash memory.
    • The dimensions of this module are 11.5 x 19.5 x 2.5 mm.
    • This module has SMT wads for tranquil and unswerving PCB escalating.

RN4020 Power Modes

  • The RN4020 can function in a diversity of power conditions, dependent upon the solicitation required.

  • These are the main four power modes of RN4020.

Idle: 

This situation passes in on power-up when WAKE_SW in one state and signifies the condition where Command style is energetic.

Active RF:

This power state comes in upon any compulsory RF action (TX/RX) through publicity, detection, coupling, assembly, etc.

Deep Sleep:

This is the less-power modes reinforced by the RN4020. The main topographies of this state-run is that publicizing packages are still airing.

To place the RN4020 in Deep Sleep method after Idle state you should follow some rules.

  • Put the WAKW-HW pin in low condition.
  • Wrench the WAKE-SW pin in zero condition.

Dormant:

It is the last power mode which reinforced by the RN4020.

To place the RN4020 in this mode you should follow some rules.

  • WAKE-HW pin should be in a low state.
  • After this put o command.
  • Then instantaneously wrench the WAKE_SW pin to low state.introduction to rn4020, rn4020 pinout,rn4020 working, rn4020 features, rn4020 applications, rn4020
