21.3.4î™–î™–î™–î™–Notes
• The +UHTTPC command has a default timeout setting set to 180 s. The timeout is counted from the last
successful network read or send operation performed by the HTTP application, so in a real timeout case
the application might be executing a command more than 180 s.
• The data string must not exceed the maximum length of 128 bytes.

If
