Response to command "AT"

Hi,

I use the WIzFi220 on the evaluation board WizFi210-EVB. The FW version is 1.1.1.0.
When I send the command “AT” from a terminal program on a PC I receive this from the module:

0x61 0x74 0x0D 0x0D 0x0A 0x5B 0x4F 0x4B 0x5D 0x0D 0x0A 0x0A 0x0D 0x0A

When I should receive this ( according to the document WizFi210Programmer’s Guide version 1.31 page 2-1 ):

0x61 0x74 0x0D 0x0D 0x0A 0x5B 0x4F 0x4B 0x5D 0x0D 0x0A

So I receive 3 extra bytes ( 0x0A 0x0D 0x0A ). Why does the module send these 3 extra bytes. Is this a setting maybe?

Thanks!

Hello

I think that it is related with your serial terminal program.
Please check your-sent-data. (expecially and ).


Hi,

I have the same problem with my TCP Client. If I send a string the WizFi220 attaching a Carriage Return and Line Feed…
Which TCP Client should I use and is it just the problem of the TCP Client or of the WizFi220.

Thanks
