HMonitor is a serial monitor for compatible Bluetooth 4.0 (BLE) Devices.
Works with HM-10 (HMSoft).
To make the HM-10 work on AT-commands via Bluetooth, it once has to be set to AT+MODE2 from a conventional serial monitor of a connected Computer. Once set, the HM-10 will handle AT-commands from the iPhone via Bluetooth.
A PDF-list of all available AT-commands depending on the certain HM-10 Software can be found on http://www.jnhuamao.cn/index_en.asp?ID=1. Just look for the BLE Bluetooth datasheet link.
The HM-10 will pass received Bluetooth-commands even to UART-connected microcontrollers, such as Arduino devices.
