When I type the "AT, AT+RST or AT+GMR" commands the unit works fine.
When I type "AT+CMODE, AT+CWJAP or CW+LAP" I get an error message.
Any ideas would be greatly appreciated.

For most commands:

• Test if a command is supported and what parameters are valid: AT+<COMMAND>=?
• Query the current setting: AT+<COMMAND>?
• Set a setting with a value: AT+<COMMAND>=<value>

What is the exact message when you enter:

Does it just say "ERROR" (in that case the firmware version doesn't support this command)?
Or perhaps you forgot the question-mark after the command (which means it's a query)?

You do know that you need to use upper case characters, make no mistakes (don't use backspace to correct them) and CTRL+M-J to process the command?
