Low Power RFID Solution Demo on the Nordic nRF52 Series

This blog is to use the ESB for building the RFID demo. On every 2 seconds, the PTX would send 4 times RFID data out. Here is the demo code at the github https://github.com/jimmywong2003/nrf52-esb-rtc-low-power static void send_packet(uint8_t *data_ptr, uint32_t length) { static nrf_esb_payload_t esb_payload; esb_payload.noack = 0; esb_payload.pipe = 0; memcpy(esb_payload.data, data_ptr, length); esb_payload.length = … Continue reading Low Power RFID Solution Demo on the Nordic nRF52 Series

Enhanced ShockBurst ESB Protocol on nRF52 Series

This blog is to describe more about the proprietary radio protocol on the nRF52 series. On the Nordic nRF5 SDK, it has two difference protocols. Enhanced ShockBurst (ESB)Gazell In this blog, I would mainly focus on the ESB because it provides full source code instead of library. Also, it can do much more flexible to … Continue reading Enhanced ShockBurst ESB Protocol on nRF52 Series
