Hi,
I'm very interested in working with you. I can develop to you the working code to read MiFare and NFC badges with the Elechouse PN532 NFC module V3 connected to a ESP32 over I2C and over SPI without problems. However, to develop the code for the MDR badge I would like to get a little more information. Could you share with me the specifications of the badges you are using?
I have advanced knowledge in C and C++ software development for Arduino, ESP8266, ESP32 and ARM microcontrollers. In addition, I have worked previously in similar projects for IoT, IoMT and digital signal processing applications using various communication protocols such as: SPI, I2C, USB, UART, MQTT, RS232 and ModBUS. Always with excellent results.
Please contact me to discuss the details of your proyect. Bugs resolving cost are included in my bid amount.
Looking foward to work with you.
Best regards,
Javier Inojosa.
