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.

MDBT50Q Ceramic Antenna Series:

MDBT50Q-1MEN:
Equipped with a ceramic antenna module suitable for long-distance or complex environment wireless transmission.

MDBT50Q-P PCB Antenna Series:
