Wireless Protocol Support and Rich Peripheral Flexibility of nRF52832

In order to fully grasp the functionality of the nRF52382, we’d like to tackle its protocol support and flexibility. In that way, we can prevent the occurrences of failure during the application.

Wireless Protocol Support

The concurrent multiprotocol is supported by the nRF52832 SoC. In order to allow handsets to provide, equip, manage, and operate mesh nodes, Bluetooth net, and Bluetooth LE can coexist. Highly specialized interfaces operating at 2.4 GHz, ANT, and NFC are also accessible. It is compatible with Bluetooth Low Energy and has a 2 Mbps significantly higher rate.

Rich Peripheral Flexibility

To enable complex single-board solutions, the nRF52832 has a wide range of interfaces and peripherals. The whole range of network communication is covered. Furthermore, PWMs, QDEC, and dual PDM electronic microphone ports are functionalities that are built within the chip. EasyDMA memory architecture is supported by all endpoints and connectors, increasing efficiency, performance, and accessibility.

nRF52832 Programming

In this sector, we will dissect how to program the nRF52832 via a bootloader.

Using a dedicated JTAG developer to install code onto the nRF52832 Breakout is unnecessary because it comes with a sequential bootloader already configured. Nonetheless, this setup of a serial link between the desktop and the breakout does require an FTDI Basic Device.

Linking the FTDI and Breakout

It connects to the 6-pin serial interface of the nRF52832 using the FTDI Basic. The boards should be slotted together after matching the “BLK” and “GRN” markings. Afterward, the red power LED ought to start to light up. Check the FTDI-VCC EN switch on the board’s rear to see if it hasn’t been disabled or if it won’t turn up.

Triggering the Bootloader

Since the nRF52832 doesn’t offer an auto-reset function similar to the Arduino board, it needs to sample the state of the GPIO 6 during the bootup. After that, pin 6 must be minimal to launch into the bootloader; otherwise, it runs into the pre-programmed software. Therefore, one must refresh the device while pressing the pin 6 switches to launching the nRF52832 into its bootloader.

The bootloader reboot trick is as follows in the step-by-step format:

  1. Hold down the 06 and Reboot switches simultaneously.
  2. Reset the device.
  3. Check to see whether the blue (pin 7) LED starts flickering.
  4. Disengage the user button with the 06 labels.

The blue LED on pin 7 of the nRF52832 should begin to flicker in what is known as the “ticking bomb” rhythm when the device is in bootloader status.

We receive this in exchange for not using pricey JTAG programmers, which is to say that it is a little complicated and highly irritating to do before each procedure. One can upload code to the chip using Arduino’s “Upload” option when you’ve already typed the bootloader.

Uploading the Blink

We suggest attempting to submit a simple blinking demonstration after linking the flickering line to the onboard LED on pin 7. Below is a copy of the code one can paste into their device.

const int ledPin = 7;

void setup()


    pinMode(ledPin, OUTPUT);


void loop()


    digitalWrite(ledPin, HIGH);


    digitalWrite(ledPin, LOW);
