Review on 📡 HiLetgo HC-05 Wireless Bluetooth RF Transceiver Module: Master-Slave Integrated BT Module for Arduino (2pcs) by Ben Balas

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 website for addressing programming protocols. I haven't gotten far enough to determine that they actually speak to each other as both ADDR's are different.
