APPA Multimeters
Hand multimeters, bench versameters and current clamps with optical serial (USB) and BLE interface supported by the "appa-dmm" driver.
The driver supporting these APPA-based devices ("appa-dmm" in sigrok) has been created and will be included in mainline sigrok once it passes acception (see developement repository github.com/Cymaphore/libsigrok branch appa-dmm).

Note: * BLE-Support on individual models
Examples: Establish data connection between sigrok and MM 12 (APPA 506B)
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 is loadad and up (should happen automatically). /dev/ttyUSB0 is used as an example.
List devices, if unsure what the serial port is:
# sigrok-cli --list-serial /dev/ttyUSB0 CP2102 USB to UART Bridge Controller - 2020y000231
Scan for MM 12 with USB/Serial connection:
$ sigrok-cli -d benning-dmm:conn=/dev/ttyUSB0 --scan
Show readings from connected meter:
$ sigrok-cli -d benning-dmm:conn=/dev/ttyUSB0 --continuous
Open in SmuView:
$ smuview --driver benning-dmm: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:
# sudo sigrok-cli --list-serial bt/appa-dmm/18-7A-93-BF-47-62 BENNING MM12 (BLE)
If your OS / UI supports it, you can also use the Bluetooth scanning capability from the system tray and pick the MAC address from the details there.
"18:7A:93:BF:47:62" acts as an example for the device address you will find. 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, as seen in the scanning result: bt/appa-dmm/18-7A-93-BF-47-62
Scan for MM 12 with BLE connection:
$ sigrok-cli -d benning-dmm:conn=bt/appa-dmm/18-7A-93-BF-47-62 --scan
Show readings from connected meter:
$ sigrok-cli -d benning-dmm:conn=bt/appa-dmm/18-7A-93-BF-47-62 --continuous
Open in SmuView:
$ smuview --driver benning-dmm:conn=bt/appa-dmm/18-7A-93-BF-47-62
