When the network tends to be dense, the number of nodes decreases, and the minimum value is 96.8MAX packet length63Byte (including port address information)9Transmission capacityThe transmission rate is higher when only one node sends data:
Because the routing information of the transmitted packet occupies a certain bandwidth, the longer the length of each packet, the higher the transmission efficiency.
2400 Bit/s when each package contains 3 bytes of data.
10KBit/s when each package contains 30 bytes of data.13MAX send rate250KBit/s14Packet retransmission timesUp to 15 times, at least 5 times when the network load is high15Air delaySingle-hop between nodes, less than 10mS16Transmit power4. 5dBm17Operating Voltage2. 5V~3. 6V18Working currentLess than 30mA19Antenna interfacePCB antenna

Please use it empty when the user is using it.TestTx4Enter test information in test mode, which will be output as a controllable IO port when the user uses it.TestRx5Enter test information in test mode, which will be output as a controllable IO port when the user uses it.Gnd6, 9,16GroundVcc7,8Power supplyBaudReset12If this pin is grounded first and then the module is started, the module will force a 115200 default baud rate to operate. In this mode, the baud rate of the module can be read or set. The baud rate read is the baud rate previously set by the module, not 115200. If the baud rate setting is not performed, the module will be restarted again. Work with the previously set baud rate.Tx14Uart output of the moduleRx15Uart input of the module
