|3||Working frequency||2400~2450MHz (16 channels total)|
|4||Communication Interface||UART serial port (supports 13 baud rates, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600, 115200, 230400, 125000, 250000, 500000)|
|5||Self-organizing network hops||<=15 jump|
|6||Single hop transmission distance||70 meters (out of the air, no occlusion test)|
|7||Number of points that can be accommodated||The typical value is 190. When the network tends to be dense, the number of nodes decreases, and the minimum value is 96.|
|8||MAX packet length||63Byte (including port address information)|
|9||Transmission capacity||The 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.
|13||MAX send rate||250KBit/s|
|14||Packet retransmission times||Up to 15 times, at least 5 times when the network load is high|
|15||Air delay||Single-hop between nodes, less than 10mS|
|16||Transmit power||4. 5dBm|
|17||Operating Voltage||2. 5V~3. 6V|
|18||Working current||Less than 30mA|
|19||Antenna interface||PCB antenna|
|Pin name||Pin position||Significance|
|NoUsed||1, 2,10,11,13||Not used, please keep it empty (empty refers to not connected to any circuit)|
|TestMode||3||Test mode, when working in normal mode in empty, grounding works in test mode. Please use it empty when the user is using it.|
|TestTx||4||Enter test information in test mode, which will be output as a controllable IO port when the user uses it.|
|TestRx||5||Enter test information in test mode, which will be output as a controllable IO port when the user uses it.|
|BaudReset||12||If 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.|
|Tx||14||Uart output of the module|
|Rx||15||Uart input of the module|
