Star network module IoT application scheme based on CC1310 chip

CC1310 chip wireless module overview Chengdu Ebyte Electronic Technology Co., Ltd. is an innovative company dedicated to independent research and development and customer customization needs. The E70 series wireless module is a star networking solution launched by Ebyte. The wireless A coordinator of module products can support up to 200 nodes to communicate with it.

This type of wireless module product currently mainly promotes 433MHz-1W. For other frequency schemes and power schemes, you can directly consult Chengdu Ebyte. The wireless module integrates the coordinator and the terminal, and the working mode switching is realized through the external control mode or the upper computer setting. The module provides long-distance and high-speed transmission methods, and long and short address communication settings. All settings can be set using industry standard AT commands or the host computer provided by Ebyte, which simplifies user use. The star network consists of two types of network devices—the central node and the terminal node. The central node is the hub of the entire star network. All terminal nodes are connected to the central node through wireless or wired forms to communicate with the central node. Terminal nodes cannot communicate with each other, and must be forwarded through the central node, so as to achieve mutual communication between terminal nodes.

2. CC1310 wireless module application The CC1310 chip module is a star networking mode implemented in accordance with the IEEE 802.15.4 standard. The wireless module solution has a large processing gain, so it has strong anti-interference and anti-multipath delay expansion capabilities. The internal use of frequency fast change mode can easily avoid the influence of known interference sources or signal sources. The power consumption of the CC1310 module is very low. According to the actual test of Chengdu Ebyte 433MHz-1W, its sleep current is only 4uA, and the receiving current is only 14mA. At the same time, in star network applications, if it is applied in low power consumption scenarios , you can directly select the sleep node mode to achieve low power consumption. The star networking solution is TI 15.4-Stack protocol. The wireless module currently supports 433MHz, 868MHz, and 915MH frequency bands. At the same time, for different application solutions of users, the E70-433NW30S star networking module adopts two modes of long-distance and standard transmission. The distance transmission rate is low, but the transmission stability is high and the communication distance is long; the standard transmission mode has a high transmission rate, but relatively speaking, the communication distance is relatively short. The CC1310 module is based on TI 15.4Stack star networking applications. Compared with 2.4GHz star networking applications (for example: Zigbee ad hoc network), it has significant advantages in long-distance communication and wall penetration capabilities. At the same time, TI 15.4Stack The star network can provide a larger coverage area. Increasing the transmission power means providing a longer communication distance, thereby improving network coverage, which can be adapted to industrial and smart city solutions. E70 (433NW30S) adopts the frequency hopping scheme, which is realized by changing the receiving frequency band of the equipment in different time periods. Compared with the non-frequency hopping scheme, its anti-interference ability is greatly increased. In practical applications, the slave can send data to the master at the same time, without polling one by one with complicated settings in the program, which improves the transmission efficiency and development progress, and at the same time ensures that the data of the slave can be sent to the master at high speed and stably. In order to expand the application, Chengdu Ebyte has launched a series of wireless data transmission module products such as TTL interface, Ethernet interface, and RS485/RS232 interface.
