Sun Zhongjie （Nanjing Silan Microelectronics Technology Co., Ltd.，Jiangsu Nanjing 210042） Abstract：In recent years，how to reasonably use multiple rates for communication in BLE has received wide attention， but most studies focus on performance optimization at a single communication rate， which has a certain impact on the throughput of BLE device systems。To address these issues， a RSSI … Read more
I believe the cross-platform abstraction provided by ZephyrRTOS is a very important feature. Of course, the abstraction itself also brings a more complex software architecture and a steeper learning curve. Recently, I tried to use the nRF52840 to create a low-power Bluetooth + LTE + GNSS board. Initially, the distributor lent me an nRF52840 DK, … Read more
