Advanced Pulse Width Modulation (PWM) on Nordic nRF52 Series

In this blog, I would like to describe more details how to use the PWM module on Nordic nRF52 Series MCU. Basically, nRF52 has started to support hardware PWM modules. If someone would like to generate some complicated duty cycle or waveform, it is better to know how to use the PWM module inside nRF52.… Continue reading Advanced Pulse Width Modulation (PWM) on Nordic nRF52 Series

External SPI Flash Bootloader on nRF52 Series

This blog is to demo how to use the external SPI flash for Device Firmware Upgrade (DFU) on the nRF52 Series. The target is to minimize the size of the bootloader particular on the nRF52810. The total size of the bootloader + its setting is only 12KB comparing to original bootloader SDK (32KB). Note: this… Continue reading External SPI Flash Bootloader 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

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
