[Evaluation of EC-01F-Kit, the NB-IoT development board of Anxinke] 02. Debugging EC-01F Socket communication with the serial port assistant [Copy link]

In the previous chapter, we mentioned that the communication between PC and EC-01F has been established. Now we start to create Socket communication.

1 Test baud rate

AT\r

2 Turn off echo

ATE0\r

3 Check whether the SIM card is normal

AT+ECICCID\r

4 Attach to the network (before attaching to the network, the following conditions must be met: the network card has traffic, the antenna is an NB-IoT antenna, and the SIM card ID can be queried)

AT+CGATT=1\r

5 Register APNID (successful network attachment proves that you can access the network, and then set APNID to access the Internet)

AT+CGDCONT=1,"IP","CMNET"\r

6 Activate the network (After successful registration, you can directly activate the network and officially connect to the Internet. (Network activation requires successful APNID testing))

AT+CGACT=1\r

7 Create a socket for TCP protocol

AT+SKTCREATE=1,1,6\r (1 is IPV4, 1 is TCP mode, 6 is IPPROTO_TCP TCP protocol definition)

8. Use Peanut Shell to create intranet penetration

9 Initiate connection (fd: fd, addr, port returned when creating the socket)

AT+SKTCONNECT=0,"116.62.200.72",10520\r

10 Sending Data

AT+SKTSEND=0,5,3132333435\r

11 Close Socket

AT+SKTDELETE=0\r
