[0004] The present invention designs a gateway based on nRF240L01 and a general-purpose WiFi chip, which has two meanings: on the one hand, it realizes the traditional nRF240L01-based application to standard WiFi wireless network access, so that the traditional nRF2401 application system and the standard system can be interconnected. On the other hand, the number of channels in the existing WiFi system is limited (13 in my country), and relatively complex technologies such as code division multiple access and time division multiple access are required in large-scale wireless sensor network applications

Embodiment Construction
[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0021] refer to figure 1 As shown, a WiFi / double 24L01 gateway, the gateway includes two sets of radio frequency transceiver systems with nRF24L01 chips as the core, WiFi communication systems with the ESP8266 module as the core, and peripheral circuits, wherein the nRF24L01 chip communicates with the The ESP8266 modules are connected, and the radio frequency transceiver system with the nRF24L01 chip as the core constitutes the peripheral equipment of the ESP8266 module. In the ESP8266 module, the SPI interface chip selection signal terminals U0TXD and GPIO0 are respectively connected with the chip selection signal terminals of two nRF24L01 chips. The GPIO5 terminals in the ESP8266 module are respectively connected to the CE terminals of two nRF24L01 chips. The GPIO5 terminals are combined with the chip selection signal terminals U0...

The invention relates to a WiFi / dual 24L01 gateway. The gateway comprises two sets of radio frequency transmit-receive systems with nRF 24L01 chips as cores, a WiFi communication system with an ESP8266 module as the core, and a peripheral circuit. The nRF 24L01 chips are connected with the ESP8266 module through a serial peripheral interface (SPI). The radio frequency transmit-receive systems with the nRF 24L01 chips as the cores form peripheral equipment of the ESP8266 module. SPI chip selection signal ends U0TXD and GPIO0 in the ESP8266 module are respectively connected with chip selection signal ends of two nRF 24L01 chips. A GPIO5 end in the ESP8266 module is connected with CE ends of the two nRF 24L01 chips. The GPIO5 end is combined with the chip selection signal ends U0TXD and GPIO0 so as to be used for selecting the working mode of the nRF 24L01. Through adoption of the WiFi / dual 24L01 gateway, the conventional nRF 2401 / L01 based chip is applied to standard WiFi wireless network access, and the WiFi / dual 24L01 gateway can better meet the application requirements of multipoint communication, grouping, frequency hopping and so on.
Description
technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a WiFi / double 24L01 gateway. Background technique [0002] With its advantages of easy deployment, convenient expansion, and low maintenance costs, wireless sensor networks have been widely used, and some typical products and solutions have gradually formed their own characteristics and markets. Among them, the nRF24L01 chip product has obtained better application with its own characteristics, and gradually formed its own market in the field of low-cost short-distance wireless communication. [0003] On the other hand, nRF240L01 has limited functions and has been used in the low-end market for a long time. Most of them are customized applications without standard protocols. There are deficiencies and limitations in further large-scale applications and networking. How to inherit the original application and market while overcoming technical limitations ...
