No. 1268	[140210-0001FE] Re: UDP mode in AT-Command	2014-02-10

Dear DuongLH, Here are answers to your questions below. Question 1, 2: Unfortunately, AT command mode does not support UDP communcation. Question 3: when you use the client mode, the local port is changed to source port number automatically. so, if you want to use the server mode after using the client mode, you should set local port number(at+plip) again. I am sorry for any inconvenience you may experience. Have a nice day. Thank you. > DuongLH wrote: > ------------------------------------ > Hi dear, > > I am using CSW-M85 Serial WLAN Module (V2.2B). In the project I am doing, this module is connected to a MCU through RS232. So I would like to configure and control this module by MCU through RS232 automatically in AT-Command mode without any software (e.g. ezManager V3.2E). > > I do not know how to set UDP mode without using ezManager.

In TCP Server/Client communication in AT-Command mode, I configured the Local IP port (e.g. 1470), but after the first time using "ATD" command (for establishing the TCP Server connection from CSW-M85 to my Server), and then disconnect from Server, this Local Port was changed automatically into another number. This problem caused my client device could not make TCP connection to CSW-M85 by using its Local Port(1470). Could you solve this problem for me? > > Thanks in advanced.
