Setting and query the access way of K6 IP, IP/subnet masks/gateway parameters

Get IP address , gateway address, DNS server and other information from the gateway server to easy the step for setting IP address, DHCP adopted to the environment that have no special requirement to IP.

Advantage: accessing the device equipment with the DHCP server such as router can communicate directly. Reduce the hassle of setting IP address and subnet masks.

Disadvantage: accessing the device with no DHCP server such as computer directly, K6 can not work.

2. Subnet masks used to determine the host number and the network number, indicates the number of subnet and determine the flag within the subnet. The subnet masks needed to set, usually we use the subnet masks: 255.255.255.0, the network number is the former 24, the holder name is the last 8, number of subnet is 255, the module IP is in the range of 255, and then we are sure that the module IP is in this subnet.

3. Gateway is the net port of the LAN. If you connect the router to access the internet, the gateway is the router IP address, setting wrong and can not access into the net. No device such as router and no setting, keep the default.

4.1.2. DNS Server Address

DNS servers are used to convert domain names into IP addresses that are recognized by the network. DNS server address can be set, which can realize domain name resolution in the case of imperfect local domain name server. Users can also set the address of specific DNS server according to requirements. When K6 needs domain name resolution, it will submit the resolution request to the DNS server set.Using is more flexible and reliable.

In static IP mode, the default DNS server address is 208.67.222.222, and in DHCP mode, the DNS server address is obtained automatically. Version 4015 above support domain name server address can be set.

Diagram 4.2.1-1 TCP Client

It has to be connected before transferring data.

1) In TCP Client Mode, K6 connects TCP Server actively, establish a connection to transmit date. According to the TCP protocol related rule, there difference for TCP client between connect and disconnect, to make sure the data exchange more stable. Usually used in the data interaction between device and server, which is the most common form of network communication.

2) In TCP Client Mode, support the function of identifying disconnected link. When connected, it will send keepalive package every 15s. If unconnected, it can be detected timely and enforce K6 to disconnect the former link to establish a new one.

3) When K6 try to connect remote server, if the local port number is not “0" ,it will establish a connection with the

same source port every time.

4) Support synchronizing baud rate, USR-cloud and short connection function.

5) In a LAN, if the K6 is static IP, please keep K6 IP stay in the same network segment with gateway, and setting the gateway IP, otherwise can not work as normal.

6) note:keepalive, synchronizing baud rate and USR-cloud are more on the below.

7)Communication example

① Software setting, take the K6 as a TCP client, remote IP:192.168.0.201,(for my PC is 172.16.11.8, so for the next testing ,change remote IP to 172.16.11.8) remote port:8234, then save it. Research to make sure the parameters are right. Also you can set work mode, remote IP and remote port in the webpage then save and restart.

4.3.1. Basic Parameters

USR-K6 User Manual www.usriot.com

Diagram 4.3.1-1 Basic Parameters

Serial port basic parameters including: baud rate; data bits; stop bits; parity.

1.Baud rate: communicating speed of serial port, can be set from 600~460.8Kbps, support random baud rate.

2.Data bits:the range of it from 5to 8.

3.Stop bits:can set from 1 to 2.

4.Parity: support none, odd, even, mark and space

4.3.2. Serial Port Framing

Since the data on the network is transmitted in the unit of data frames, it is necessary to send the frame data via serial port to the network, so as to transmit data more efficiently and quickly.K6 packages serial port data according to fixed packaging length and packaging time during data transmission.The default K6 packaging time is 4 bytes of packaging time and 400 bytes of packaging length.

Jinan USR IOT Technology Limited 38 / 107 [email protected]

USR-K6 User Manual www.usriot.com

The frame mechanism of serial port is based on the packaging time and the packaging length.

1. Serial port packaging time: the default is 4 bytes of send time.

The default package time of K6, the interval that serial port receive time more than 4 bytes packaging time, K6 packaging sending. E.g. baud rate is 115200K time for 4 bytes is 0.4ms, if the value less than 0.1ms, the package time calculate as 0.1ms. A formula to calculate as fellows:

T＝1/baud rate*10*4

2. Serial port package length: default package length is 400 bytes

When K6 receive data from webpage, and then send to serial port. For the limited of the serial speed, the user need to control the flow, otherwise data overflow problems can be occur and drop the package. So when send data from network to serial port, please calculate the flow.

Calculate way: if sending M bytes need N s. the way to check for possible overflow methods (if the net situation is ok, the time can be ignored ). The time for M bytes:

T＝1/baud rate*10*m

If there is no overflow, M bytes of data must be transmit within Ns, then N>2T is require for K6 to work properly.

4.3.3. RFC2217

Similar RFC2217 is a simple RFC2217 protocol, working with the VCOM and changing serial port parameters candynamically to realize the communication with variable serial port parameters.

Enable this function, using USR-VCOM can open this function,which can realize the serial baud of the PC software and K6 automatically match. No need to pay attention to serial port baud rate setting.

5.3. AT Command

AT command is used for controlling module. You can use AT command to configure and query the settings. Later we will interpret the type in detail.

5.3.1. AT Command Overview

AT+ command is the command collection that perform the command transport using UART and module under the order mode. Later we will interpret the type in detail.

Powered successfully, we can setting the module with UART.

The default UART port parameters of the module are: baud rate1152000, no parity, data 8 and stop 1.

Instr

AT command test tools.UART interface recommand to use secureCRT software tool or USR pro APP. Below are using the secureCRT with UART to perform.

From transparent transport to order mode need two step as below:

 Fill “+++”in the UART. After the module receive the “++++”,it will send a “a” to confirm;

 Fill the confirming “a” in the UART, after the module receive and send “+ok”, enter the command mode.

Instr: if no feedback after fill “++++”and “a”, as the above.

Fill “+++”and “a” need to achieve in the time to reduce the chance of entering command mode while working normally accidentally. Detail requirement are as fellows.

2. After receive “a” feedback a “a”in 3s.

3. After the module receive “a, send “ok”to the device, and enter “AT”command

4. After the device receive “+ok” and know the module enter the AT command mode, then send AT command.
