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
Using External Flash to Store bonding info on nRF52 Series
This blog is to show how to use the external flash for storing the bonding information instead of using the internal flash. I would base on the Nordic SDK 16.0 and use the nRF52840 DK as the baseline to show how it works. By using the external flash for bonding storage, it can save at… Continue reading Using External Flash to Store bonding info on nRF52 Series
BLE Scanner with RSSI and MAC Address
This blog is to give a demo how to scan the ble advertiser and show the RSSI and MAC address in sorting order. It is the feature similar to the mobile phone. For example, as below, the scanner is kept to get the nearby advertiser. It would get all the corresponding advertising payload, peer address… Continue reading BLE Scanner with RSSI and MAC Address
