HM-10 BLE Module
This BLE 4.0 module can be used to communicate with desktop computers, smartphones, table computers and even other embedded systems. The HM-10 bluetooth chip is a highly customizable bluetooth chip with AT commands. You can also modify the role between master or slave mode as well as change the baud rate.
The onboard LED will flash slowly when the module is not connected and paired with a remote device, at this time you can use the AT commands to change the configuration.
Note: HM-10 can only recognize AT commands which are all uppercase or lowercase.
