No. 1295	Re: cannot access atcommand mode	2014-11-14

Hello, This is a technical support team of Sollae Systems. You can only change "ATC-AT command" communication mode in the ezManager. Command state The CSE-M53N is in command state right after when power turns on. In this mode, incoming serial data is treated as AT command. On-line state When TCP connection is established, it automatically operates in On-line State. So incoming serial data is sent to the server. "+++" changes from the on-line state to command state. After the setup of "+++", you cannot send data to server. If you want to send data to server, you can change to on-line state by using ATO Command. Please refer to the link below for more detail about AT Command(ATC) Mode. http://www.eztcp.com/documents/application/an_atc_mode_en.pdf Thank you. > Tran Quoc Trung wrote: > ------------------------------------ > Hi, > I had bought a module csem53n of your company. > But i cannot go to AT mode by using command "+++" in hyperterminal, otherwise i must use software ezManager53 and change to mode AT command to use AT command in hyperterminal.
