Standard protocol not used

When entering AT mode, some commands known as "standard protocol" ie. AT+UART, AT+URT? or AT+NAME? will not return an answer. The only commands that returned a response were AT+NAME, AT+BAUD, AT+ROLE, AT+ADDR, AT+PIN. I was able to change a device name by typing AT+NAME[EXAMPLE], then confirmed the EXAMPLE confirmation prompt. For example, if I typed ... AT+NAME=[EXAMPLE], that would confirm that the name was "EXAMPLE"; Expect a board with ROLE = 1. Both have 0. Zero information on the company…

Pros
  • Good thing
Cons
  • Not satisfied

Nice Electronics is the best network adapter

It was a bit difficult to get AT mode to respond but after figuring it out I thought these were good modules for basic wireless communication. An included documentation would be nice.

Pros
  • Many will fit
Cons
  • Weight

A must for offline Arduino projects!

I am building robots for a hobby and it can be annoying that everything is packaged nicely only to have to take it apart to get to the USB port so you can update your code or receive debug output. No longer! Now I can connect to my project and do everything wirelessly. Worked out of the box. Keep in mind that you may need to change the baud rate to make it work with the serial device you are connecting to. Very happy with this purchase.

Pros
  • Not cheap but decent
Cons
  • For the old

Not all AT commands are available

After spending several hours looking for a solution I gave up. While many AT commands work, some important ones don't. Most importantly, these modules could not be programmed to be bound to a specific address. The AT command for BIND did not return "OK" and did not change the default value of 0:0:0. And I couldn't change the baud rate with the UART command - always went back to 4800. Unfortunately I can't recommend a better solution until I've tried another brand.

Pros
  • Not only useful for the intended purpose
Cons
  • Will be added later
