How to upgrade Specify FW from SPI flash on nRF52 Series

This blog is to show how to use the SPI bootloader to load the specify firmware from SPI flash for device firmware upgrade. Following up the blog (SPI bootloader), I would continuous to use the nRF52840 DK board and use its onboard qspi flash as SPI flash. For example, there are 3 difference application firmware… Continue reading How to upgrade Specify FW from SPI flash on nRF52 Series

Maximum BLE Throughput with IOS

This blog is to show the BLE throughput on different user scenarios. I would also show the maximum throughput in the real world, particularly how fast the BLE communication with IOS devices. I would use 2 x nRF52840 DK for the central and peripheral bi direction communication and print out the live throughput. After that,… Continue reading Maximum BLE Throughput with IOS

OLED display support for nRF52 Series

This blog is to add the OLED display on the nRF52 DK board. I would give the example code how to use the GFX and adafruit library on the Nordic nRF52. On the Nordic nRF5 SDK, it contains the GFX library with the LCD 320x240. https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/lib_gfx.html GFX library The GFX library provides support for drawing… Continue reading OLED display support for nRF52 Series

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
