Design and Implementation of Management of Multi-Connection Timing Based on Bluetooth Low Energy
Kai Yang, Yong Lv · 2022
For Bluetooth Low Energy application, difficult setting and complicated management of timing parameters in multi-connection between master and slave nodes is obvious. For this situation, a method based on time slice was proposed for updating slot parameters to guarantee the reliability of multiple connections. It determines the value of multi-slots period and other timing parameters depending on the quantitative relationship between the minimum(maximum) connection interval of every connection and multi-slot period. In this paper, a reliable writing and reading method for multi-connection between master and slaves was designed and implemented in TI CC2640R2F platform, on which we made some performance measurements of above updating method. The experimental results show that the proposed method for updating slot parameters based on the writing and reading procedure behaves well in multiple connections for Bluetooth Low Energy.
