Modular Data Injection Architecture for Embedded Systems

Published at September 5, 2025 ·  5 min read

Designing complex embedded systems — such as IoT devices, medical products, or industrial controllers — often requires supporting multiple hardware platforms: MCUs, Embedded Linux systems, and sometimes even mock environments for testing. To achieve clean separation between core logic and platform-specific implementations, I designed a modular data injection architecture based on virtual interfaces and dynamic backend registration. This post summarizes the approach and presents a practical C++ implementation of this architecture....

Data streaming between two BLE devices: PSoc6 and nRF52832

Published at September 10, 2022 ·  3 min read

I had a project where I had to stream data between two BLE devices. The data source was connected to PSoc6 and sent using its BLE transceiver to the destination device, nRF52832. Usually but not must, the peripheral devices are used as a GATT client, and the central machines are used as a GATT server. Therefore, I set the PSoc6 (The data source) as the central device (client) and the nRF52832 as the peripheral device (server)....

Setup UART BLE using Nordic nrf52832

Published at September 16, 2021 ·  4 min read

I have played with Murata’s MBN52832 module BLE module. This module is based on a Nordic chipset (nRF52832), it has BLE and NFC capabilities and MCU with cortex-m4 to manage the radio operation. The module comes with a demo firmware without an AT Command interface, and the user has to write its application. However, the SW flexibility allows creating a standalone application with BLE and NFC without using a host device like a PC to operate the BLE radio....
