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!
