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

Radio Timeslot API for the Multiple Protocols

This blog is to describe more details how to use the Radio Timeslot API usage. The Radio Timeslot API was introduced since Nordic Softdevice S110v6.0 or later. It can be used to implement the concurrent multiprotocol with BLE together. All the timeslot API are based on the framework of Nordic Bluetooth Softdevice stack. For example,… Continue reading Radio Timeslot API for the Multiple Protocols
