Review on π‘ HiLetgo HC-05 Wireless Bluetooth RF Transceiver Module: Master-Slave Integrated BT Module for Arduino (2pcs) by Marcus Rash
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.
- Not only useful for the intended purpose
- Will be added later
