Review on HiLetgo Bluetooth Wireless Compatible Arduino by Brent Webb

**Updated 4/26/2021** Corrected by David S. So make sure you have Newline and Carriage Return selected in your serial IDE console in the lower right corner. out, but as David S. says, there is little to no documentation. By the way, David, you saved my skin; I was ready to be angry when I realized what was going on. This is a strange carriage return/ASCII encoding error. The device is difficult to understand, but slow. David, you are somewhat right. Just use a space after /any character and AT commands work fine.
