Introduction

“Our clients buy our products because they are reliable and easy to integrate, enabling them to quickly deploy cost-effective wireless solutions.”

Mark J. Kramer – CEO of BlueRadios®

1.1 Scope

This document along with the BlueRadios® nBlue™ Bluetooth® low energy (BLE) evaluation kit was created to enable developers and integrators an opportunity to evaluate wireless networks using BLE technology. The goal is to make the transition to BLE as seamless and as easy as possible for our clients. This document will provide module hardware details.

1.2 Background

Bluetooth low energy was designed to enable the development of low complexity, low cost wireless devices that require minimal power consumption, such as sensors and watches. These devices typically transmit very small data packets at a time, while consuming as little power as possible. Bluetooth Version 5.0 Single-mode chips implement the low energy specification and consume just a fraction of the power of classic Bluetooth (BR/EDR), allowing the short-range wireless standard to extend to coin cell battery applications.

The BlueRadios® nBlue™ modules are Bluetooth Version 5.0 compliant. The modules are designed to be built into an embedded device and to provide a simple, reliable, and low cost API interface. The module is designed to integrate with a wide range of applications and platforms.

Important Notes – Please Read Prior To Continuing

1.3 Pin Voltage Levels

▪ The maximum voltage level on any pin should not exceed 3.9V. The I/O is NOT 5V tolerant. ▪ Applying VDD to a PIO set to an output may permanently damage the module.

1.4 Firmware Updates, nBoot Bootloader and IEEE Address

All nBlue modules come programmed with a bootloader (nBoot), to enable firmware updates via nBlue Programmer (nBP), and a BlueRadios IEEE address. These elements are stored in flash and can be accidentally erased using a debugger. Once they have been erased they cannot be reprogrammed by a client, it is a factory process only. When the BlueRadios IEEE address is erased, the Nordic IEEE address stored in ROM will be used.

To protect BlueRadios IP, any firmware distributed by BlueRadios or firmware built using libraries distributed by BlueRadios will not run without the presence of the nBoot bootloader. This means BlueRadios firmware will no longer run once the bootloader has been erased. At this point the module can only be programmed with custom firmware.

For security purposes, after the bootloader is programmed into BR-LE5.0-S1A modules during production the debug interface is locked. In order to program a module using a J-Link Debugger it will then need to be unlocked, which will erase the entire flash including the module’s bootloader and IEEE address, making it incapable of performing firmware updates using nBP. For this reason, single mode BR-LE5.0-S1A firmware updates should only be performed using nBP, not a J-Link Debugger. Custom software can still be flashed using nBP, see the nBlue Programmer User’s Guide for more information.

2 Module Hardware Details

The BR-LE5.0-S1A footprint is backwards compatible to the BR-LE4.0-S2A footprint with the following exceptions:

• Power must be connected to the new VDDH pin C4. This is a required change that must be done. If a single layer board is being used a 7 mil trace can be run in between the other circular pads on the bottom of the module to connect VDD to VDDH when using normal voltage mode.

• The USB pins have been relocated from pins 15-18 to pins A4, A5, B5 and C5. Pins 15-18 are now PIOs.

• The programming/debugging pins have been relocated from pins 28 and 29 to pins F3 and F4.

RF Ground Plane: The module requires an RF ground plane on the rest of the Printed Circuit Board (PCB) area. This can be located on any layer of the PCB. For best performance, extend the RF ground plane the entire length of the board. Connect all ground pins and do not notch the ground plane around the module. The bottom of the module is grounded so be careful of vias or conductive traces located under the modules that are not soldered masked to prevent shorting. Keep metallic components, connectors, copper traces, internal layers, and ground planes away from the antenna area in 3D space!

2.3 Hardware Details

The BR-LE5.0-S1A utilizes the Nordic Semiconductor nRF52840 SoC. For detailed specifications see the nRF52840 Product Specification: https://www.nordicsemi.com/DocLib/Content/Product_Spec/nRF52840/latest/keyfeatures_html5

2.3.1 Power-up and Reset

There are no strict requirements for power up timing. To reset the module, the RESET line must be pulsed low for at least 1µS.

2.3.2 UART

UART_TX, UART_RX, UART_RTS and UART_CTS form a conventional asynchronous serial data port. Two-way hardware flow control is implemented by UART_RTS and UART_CTS. These signals operate according to normal industry convention. The signaling levels are nominal 0V and VDD and are inverted with respect to the signaling on an RS232 cable.

2.3.3 USB Interface

In addition to the UART, the module can also be controlled using AT commands through a USB CDC ACM virtual serial port. The module can be controlled through this port through AT commands and events in the same way it can over the UART.

2.3.4 PIO_14 Firmware Update Mode Trigger

PIO_14 can be used to manually put the module into firmware update mode, which allows its firmware to be updated via the UART using the nBlue Programmer (nBP) application. This can be done by setting it to VDD during power up or reset and holding it at VDD until the “nBoot” message is sent from the UART.

nBlue Programmer (nBP) is a Windows application that allows firmware to be updated on all nBlue Bluetooth 5.0 modules. Updates can be performed through the module’s UART or USB interface and Over the Air (OTA) through a BLE connection (see the OTA updates section for additional requirements.) See the nBlue Programmer User’s Guide for detailed information.

This functionality is not built into the hardware, but provided by the nBoot bootloader programmed into the module by BlueRadios. If the bootloader is erased using a debugger, PIO_14 will no longer trigger firmware update mode. See the Important notes section for more information.

2.3.13 Power Modes

** IMPORTANT **: The module can be powered in normal voltage mode (1.7-3.6V) or high voltage mode (2.5-5.5V).

In normal voltage mode, 1.7-3.6V must be connected to both VDD and VDDH. In high voltage mode, 2.5-5.5V is connected only to VDDH and in this case VDD will be the output of the internal VDDH regulator (AT.s firmware sets the VDDH output to 3.3V, but the 52840 defaults to 1.8V). In either power mode the voltage on the VDD pin will be the IO voltage, so the IO voltage can never be higher than 3.6V and is never 5V tolerant even when using VDDH. See the Internal Regulator Diagram on the next page for a visual on how the regulators connect.

** IMPORTANT **: Due to an issue with Rev 1 of the nRF52840, high voltage mode can only be used under the

following conditions: the VDDH internal DCDC converter cannot not enabled (default LDO mode only), no current is drawn from the VDD pin during power up and the VDDH rise time to 3V is < 1ms. This will be fixed in the next nRF52840 revision. See Errata 197 and 202 of the nRF52840 Rev 1 Errata for more info:

http://infocenter.nordicsemi.com/pdf/nRF52840_Rev_1_Errata_v1.1.pdf

* VBUS *: To use the BR-LE5.0-S1A as a USB peripheral, 5V must be supplied on the VBUS pin. The VBUS supply is

internally regulated to 3.3V but is only used for the USB signaling interface and USB detection. The rest of the USB peripheral is powered through the main power supply, so power must still be supplied through VDDH or VDD depending on what power mode is being used. When supplying power from a USB source only, VBUS must be connected to VDDH if USB is to be used.

INTERNAL REGULATOR DIAGRAM

Note: The inductors required to use the nRF52840’s DC/DC converters are populated inside the module - no external

inductors are required. With the AT.s firmware, the REG1 DC/DC is automatically enabled.

3 Programming/Debugging

A debugger is only needed for debugging custom embedded applications through an IDE. A debugger is not necessary for updating firmware on modules using the AT.s command set or for programming modules with custom firmware.

3.1 nBlue Programmer

nBlue™ Programmer (nBP) is a Windows application that allows firmware to be updated on all BlueRadios® nBlue™ Bluetooth 5.0 modules. Updates can be performed through the module’s UART interface, USB interface and Over the Air

(OTA) through a BLE connection. Flow control is enabled by default in order to preform firmware updates at baud rates as high as 921600 bps. The user

can disable flow control using the ASTBOOT command. With flow control disabled, the maximum baud rate is 115200. nBP does not use the SWDIO/SWDCLK Serial wire debug I/O lines.

All nBlue modules come programmed with a bootloader (nBoot), to enable firmware updates via nBlue Programmer (nBP), and a BlueRadios IEEE address. These elements are stored in flash and can be accidentally erased using a debugger. Once they have been erased, they cannot be reprogrammed by a client, it is a factory process only. When the BlueRadios IEEE address is erased, the Nordic IEEE address stored in ROM will be used.

longer run once the bootloader has been erased. At this point the module can only be programmed with custom firmware.

For security purposes, after the bootloader is programmed into BR-LE5.0-S1A module during production the debug interface is locked. In order to program a module using a J-Link Debugger it will then need to be unlocked, which will

erase the entire flash including the module’s bootloader and IEEE address, making it incapable of performing firmware

updates using nBP. For this reason, single mode BR-LE5.0-S1A firmware updates should only be performed using nBP, not a J-Link Debugger. Custom software can still be flashed using nBP, see the nBlue Programmer User’s Guide for more information.

3.2 Debugging

Debugging is done through a two-pin serial wire debug (SWD) interface. A debugger is only needed for programming/debugging a custom application and is not necessary for using the AT.s command set. If a debugger is needed a Segger J-Link can be used, or for a more cost-effective option a Nordic PCA10056 nRF52840 development board can be used. The PCA10056 has a J-Link built in and can connect to an external board using its P19 Debug out header.
