Setup

For receiving the Data from the Multimeter, I used a Bluetooth V4.0 HM-11 BLE Module connected to an Arduino pro micro running on 3,3V and 8Mhz. The module is connected to the serial interface of the Arduino and the received data are transmitted to the Usb port of the same Arduino connected to the PC.

The same way I configured the BT Module over At commands

Config of the BT module.

I used a simple Arduino program to send and receive Data to and from the module.

First you have to set the module to Cental.

To connect to the Owon B35T type AT+CONE0(Mac adress of the Multimeter)

Thats it.
