Development of a secure bootloader for encrypted OTA update via BLE. The bootloader has been developed in C in order to allow the OTA update of the Texas Instrument CC2640R2F, securely with an encrypted firmware image. The client controls the private keys and thanks to encryption techniques it is not possible to disassemble the firmwareContinue Reading CC2640R2F: Secure bootloader for encrypted OTA update
Development of a 3-Phases motor speed control via PWM controlling IGBTs. + Technology watch and R&D. + Electronics Hardware (schematics, BOM, PCB layout including SMPS) . + Embedded software in bare metal C on Microchip PIC p18f4431. + 1KW 3-phases motor. + Current sensing. + H-bridge regenerative breaking. + Flyback DCDC power supply.

Development of a BLE central; The device is setup as a client, it connects to one or multiple Bluetooth sensors at the same time and without time multiplexing. The central gathers the information, processes them and takes action accordingly. With the TI CC2640R2F it runs on a single AAA battery. [Project is still confidential, moreContinue Reading CC2640R2F: Smart Bluetooth Low Energy BLE Central (client)
