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.
Wi-Fi Alliance (WFA) – Certification program --QuickTrack -Collaboration between Solution provider & End product developer 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.
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:
Understanding Wireless Certification and Compliance:A Guide to Module and Non-Module Approval Processes
Certification and compliance: By obtaining wireless (Bluetooth) certification, manufacturers can demonstrate that their products comply with the required technical reliability. In another words, these certifications are like products’ passes, allow them legally entering the market and be able to import or export specific countries. Modular approval and Non-modular approval are two different approaches to the certification and regulatory processes for wireless communication devices.
Bluetooth Core Specification 5.4 released in 2023 introduces four significant capabilities to the existing specifications.
As the chipset of nRF5340 is built by Dual Core structure (net core and application core), we need to proceed the coding and compiling process individually to net core & application core.
