The BENNING MM 12 is a 40000 counts, CAT IV (600V) / CAT III (1000V) dual display handheld digital multimeter with USB and Bluetooth LE connectivity.

It is based on the APPA 506B, See also: APPA B (150/208/506) based Multimeters

A driver for the APPA 150/208/506-based devices ("appa-b" in sigrok) has been created and will be submitted to sigrok once ready for acception (more details in pull request #99).

Examples: Establish data connection between sigrok and MM 12

Important: Driver is not (yet) part of mainline sigrok - see this repository in github if you want to use it already.

Serial/USB

Assuming the meter is turned on, plugged in and the usb-serial driver at /dev/ttyUSB0 loadad and up (should happen automatically).

Scan for MM 12 with USB/Serial connection:

 $ sigrok-cli -d benning-mm12:conn=/dev/ttyUSB0 --scan

Show readings from connected meter:

 $ sigrok-cli -d benning-mm12:conn=/dev/ttyUSB0 --continuous

Open in SmuView:

 $ smuview --driver benning-mm12:conn=/dev/ttyUSB0

Bluetooth LE

Assuming the meter is turned on and bluetooth activated on the meter and the PC. Important: Your Bluetooth-Controller must support BLE.

Scan for BLE devices:

 # hcitool lescan
 18:7A:93:BF:47:62 BENNING MM12

18:7A:93:BF:47:62 is an example for the device address. For sigrok the ":" must be replaced by "-" for now. That device address is used for the following examples, just replace it by the address of your own meter.

The full connection string then would look like this: bt/appa-b/18-7A-93-BF-47-62

Scan for MM 12 with BLE connection:

 $ sigrok-cli -d benning-mm12:conn=bt/appa-b/18-7A-93-BF-47-62 --scan

Show readings from connected meter:

 $ sigrok-cli -d benning-mm12:conn=bt/appa-b/18-7A-93-BF-47-62 --continuous

Open in SmuView:

 $ smuview --driver benning-mm12:conn=bt/appa-b/18-7A-93-BF-47-62

Protocol

The protocol on Serial and BLE is the same for all of the APPA 150 / 208 / 506 based models.
