With the help of HC-05, you can connect with any Bluetooth-enabled device, such as a phone or laptop, or with two microcontrollers like an , <span data-mce-style=\"color: #2b00ff;\" style=\"color: #2b00ff;\"> <\/span>etc. and it requires<span style=\"color: #2b00ff;\"> <\/span>, <span style=\"color: #2b00ff;\"><\/span>to connect.<\/span><\/p>\n<p><span data-mce-style=\"font-weight: 400;\" style=\"font-weight: 400;\">Since the module uses USART to communicate, it is simple to connect to any microcontroller that supports USART. We can also set the HC-05 Bluetooth module&#8217;s default values using the command mode. Therefore, this HC-05 module can be the best option for you if you&#8217;re seeking a wireless module that can send data from your computer or mobile phone to a microcontroller or vice versa.<\/span><\/p>\n<p><span style=\"color: #000000;\">The HC-05\u00a0<\/span> <span style=\"color: #000000;\">with Baseplate is a slave-only device. \u00a0This means that it can connect to most phones and computers with Bluetooth but it cannot connect to another slave-only device such as keyboards and other <span style=\"color: #2b00ff;\"><\/span>. To connect with other slave devices a master module would be necessary such as the HC-05 module ,which can do both master and slave.<\/span><\/p>\n<p><span style=\"color: #000000;\">The slave mode in HC-05 Bluetooth cannot initiate a connection to another Bluetooth device but can accept connections.
