Optimizing functionality on nRF52 – Introducing Raytac bluetooth module with enabled Access Port Protection

Definition of Approtect (Access Port Protection):

In Nordic Semiconductor products, the enhanced APprotect feature has been integrated into the nRF52 series microcontrollers. APprotect (Access Port Protection) is a crucial security feature designed to safeguard the device’s application, compiled code, with read-back protection mechanism, against unauthorized access and modifications. This protection is essential for preventing unauthorized access and software tampering.

Effectively leveraging the improved Approtect feature on nRF52 series microcontrollers to enhance device application security and reliability is a significant concern for current developers and engineers.

This year, Raytac Corporation has launched low-energy Bluetooth modules for the third edition IC nRF52840 APprotection Solution and nRF52832 APprotection Solution.

These modules not only retain the functionalities of the original nRF52840 and nRF52832 low-energy Bluetooth modules but also comprehensively upgrade security by adding the APprotect feature to prevent hackers from accessing and rewriting programs without authorization.

Here is a detailed explanation of the nRF52 third edition low-energy Bluetooth modules by Raytac Corporation:

  • Raytac Corporation APProtection Bluetooth Module Series:

The encoding principle is to use ‘EN’ after the original model number to represent ‘encrypted’ instead of ‘V2’.

For example, in the nRF52840 series, the Raytac model MDBT50Q-1MV2 has “V2” replaced with “EN” for the third edition, hence the third edition model is named MDBT50Q-1MEN.

Wi-Fi Alliance (WFA) – Certification program –QuickTrack

Wi-Fi Alliance (WFA) – Certification program –QuickTrack

 -Collaboration between Solution provider & End product developer

Source: https://www.wi-fi.org/certification

Raytac Corp. is officially a member of Wi-Fi Alliance now!

Before stepping into Wi-Fi module selection and adoption, Wi-Fi regulatory compliance will be essential for you to know.

Let’s dig into the Wi-Fi certification program and investigate the possibility of WFA Qualified Solution (provided by Solution Provider) & WFA certificate (obtained by end product developer).

  • What benefits you (end product developer) by working with Rayta Corp. (Solution Provider) for QuickTrack program?
  1. Faster time-to-market : By using available WFA Qualified Solution (provided by solution provider) to waive (or partially waive) compliance test criteria/decrease testing days for end product (WiFi Device), shorter development days would be took before product launch.
  2. Reduce test and certification costs: it significantly reduces the cost and certification days for your project with minimal resource by working with Raytac Corp. (Solution Provider) using available WFA Qualified Solution.
  3. Avoid testing redundancies: Raytac Corp. (Solution Provider) has pre-certified the core Wi-Fi architecture and protocols in WiFi module AN7002, the necessary qualification tests has been conducted. You (end product developer) don’t need to test on those same criteria for end product (WiFi Device) if Raytac WiFi module is implemented in your end device.
  4. Allow flexibility of Wi-Fi functionality change: In case those minor change of Wi-Fi feature which is not relates to core/essential/architecture change may be raised someday in the future , QuickTrack program delivers the qualified product base (Source product) and lower cost with conformance test (QuickTrackTool) responding to the minor change. This is especially adaptive for the case end product developer has their own processor (MCU) working with Raytac NRF7002 module.
  • How QuickTrack certification program works?

QuickTrack certification program shall be completed by 2 different parties, one is solution provider and the other is end product developer.

(Refer to the following image)

As a Solution Provider, Raytac would proceed the essential and fundamental Wi-Fi protocol/compliance test and develop this into a Qualified solution so that end product developer can leverage this solution as a base (Source Product) to obtain a certificate entitled to end product developer.

Please note the conformance check (named QuickTrack Tool) would be required before Wi-Fi alliance certifies the application.

Conformance check (QuickTrack Tool) will be reviewed for the 8 Wi-Fi components.

  1. Chipset
  2. Wi-Fi Component Firmware Version
  3. Driver
  4. RF Architecture
  5. Wi-Fi Component Operation System
  6. Physical Interface
  7. RF Components
  8. Antenna

When you adopt Raytac WFA Qualified solution, the core/essential/architecture components are pre-certified in the solution, in most of cases, no further conformance test is required, you (end product developer) will be granted to obtain the certificate after a couple of days applying process.

Raytac leaves the right to Wi-Fi alliance for the conformance review (run QuickTrackTool).

  • Which membership level shall be applied in Wi-Fi alliance for being QuickTrack?

If you agree with QuickTrack program and are willing to participate in the partnership as end product developer with Raytac Corp. (solution provider), Implementer membership will be cost effective option for you.

Company like Raytac Corp. served as solution provider or require professional Wi-Fi alliance support, company own/multiple programs oriented or needs tasks management shall refer to the membership of top one – Contributor.

Criteria for Choosing Internal or External Oscillator

Bluetooth modules typically have options for a 32MHz Internal Oscillator (or some called internal crystal oscillator) and a 32.768KHz External Oscillator. The choice between the two is often influenced by specific application requirements, power consumption, accuracy, and cost considerations. Here are some basic differences between Internal and External Oscillators:

  • Internal Oscillator: (32MHz)
  • Function: The internal oscillator is embedded within the module and generates the clock signal for the Bluetooth module. This internal oscillator is typically smaller, lightweight, and reduces dependence on external components.
  • Advantages: Simplifies design, saves space, and reduces costs.
  • Disadvantages: Some applications may require higher clock stability, which the internal oscillator may not provide to the desired level of precision.
  • External Oscillator: (32.768KHz)
  • Function: An external oscillator is an independent oscillator externally connected to the module, offering higher clock stability and accuracy.
  • Advantages: Provides higher clock stability, suitable for applications with stricter timing requirements.
  • Disadvantages: Requires additional components, may occupy more space, and increases costs.

Criteria for choosing Internal or External Oscillator:

  • If the application has modest clock precision requirements, and cost and space are critical factors, choosing the internal oscillator may be suitable.
  • If the application demands higher timing precision, an external oscillator should be considered for its enhanced clock stability.

Benefits from switching between external and internal oscillator:

  • Increased Performance Requirements: If the application’s performance requirements increase, a higher-precision oscillator, such as an external oscillator, may be needed.
  • Insufficient Clock Stability: If timing stability issues arise during Bluetooth communication, upgrading to an external oscillator can provide better clock stability.

Followings are the instructions we can use to switch between internal oscillator and external oscillator for nRF5 SDK (v17.10) and NCS SDK (v2.5.2).

Keil (Keil μVision) and SES (Segger Embedded Studio) are another method commonly used Integrated Development Environments (IDEs) in the field of embedded systems development.

Choosing to use the internal crystal oscillator requires program modifications. Please refer to the following instructions for making these changes in the Keil and SES development environments.

What’s New In BT5.4 Bluetooth Specification?

Bluetooth Core Specification 5.4 released in 2023 introduces four significant capabilities to the existing specifications.

1. Periodic Advertising with Response(PAwR)

PAwR is one of the key feature. Prior to Bluetooth 5.4, connectionless bidirectional communication is not possible. PAwR now allows bidirectional transfer of data in connectionless mode between a single central device and a large number of multiple devices (up to 32,640) in a star network topology. 

2. Encrypted Adverting Data (EAD)

EAD provides a standardized approach to the secure broadcasting of data in advertising packets and enables the encrypted data over-the-star network to be decrypted only by devices that have shared the key material previously. This security feature protects PAwR communications to safeguard against data tampering, human error, and data leaks.

3. LE GATT Security Levels Characteristic(SLC)

When a GATT Client attempts to access a server attributes (characteristics, descriptors), attributes permissions are checked. If permissions are insufficient, the access is denied and all GATT features will not work properly. With SLC, the client can upgrade its security level to reattempt access of the previous failed operation. SLC enables devices to identify the security mode and level for all their GATT functionality.

4. Advertising Coding Selection

For LE Coded PHY, a Forward Error Correction (FEC) algorithm is used which results in significantly longer transmission distances. FEC parameter (S) uses one of two values (S=2 or S=8) and controls how much data is made to fix errors and how much Bluetooth range may be achieved. Prior to Bluetooth 5.4, specifying the value of the S coding parameter was not impossible. Bluetooth 5.4 allows the host to specify the value of the coding parameter S (S=2 or S=8) when the LE Coded PHY is selected for use with extended advertising.

Main beneficiary market of Bluetooth 5.4

The combination of these features enables ultra-low power, efficient radio usage and secure star networks that can be deployed in large scale ESL (Electronic Shelf Labels) and sensor applications with transferring a small amount of data. Devices accept slightly longer advertising-delay to exchange an extended battery life. It’s easy to see the retail industry as well as the market for ESL and shelf sensors will benefit greatly. ESL are devices that display pricing information for product on retail store shelves. They use small electronic paper displays powered by batteries and can replace traditional paper labels. Besides, ESL use wireless technology and a central hub device to transmit data, allowing retailers to automate pricing and replace traditional manual processes, and creating more efficient in-store operations.
