I2C MEMS Microphone with Nordic nRF52 Series

This blog is described how to connect the MEMS Microphone through I2C to Nordic NRF52 Series chipset. Hardware Requirement: NRF52840 DK Board x 1 Adafruit I2S MEMS Microphonehttps://learn.adafruit.com/adafruit-i2s-mems-microphone-breakout/ Adafruit I2S MEMS Microphone Power Pins 3V - this is the power in pin. Technically it can be powered from as low as 1.6V to 3.6V but you'll… Continue reading I2C MEMS Microphone with Nordic nRF52 Series

How to configure the number of packets per every BLE connection interval

This blog is to show the method how to configure the number of packets per each connection interval. Basically, it is very similar to the blog (https://jimmywongiot.com/2019/12/15/how-to-set-the-bandwidth-on-ble-link-connection/). I would give more details how to achieve for example 3 packet per connection interval. 3 packets per each connection interval Suppose on the Nordic nRF5 SDK, it… Continue reading How to configure the number of packets per every BLE connection interval

BLE Scan Request Filter Demo

This blog is to show how to add the scan request filter on the BLE advertiser. In BLE (bluetooth Low Energy), basically, it has two difference modes on the scanning mode. On the BLE observer, it can be either passive scanning or active scanning. If the observer plays as the active scanning, it would send… Continue reading BLE Scan Request Filter Demo

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
