Using more that one devices in the same time #56

the best option is using mqtt. I already created a project for mqtt logging you can look to it https://github.com/webspiderteam/Bluetooth_DMM_For_Windows_MQTT_Test_Project it logs values. Take a look at it.

i have 2 multimeter. this project that record current in multimeter 1 and voltage in multimeter 2. Both of multitester can pick value when i click pick button. and the value saved in csv after some of picked klick butten with export button.

ok I think we can do it. Do you have any programming skill?

what model is your multimeters?

aneng an 9002 multimeter

ok I will work on it give me some time

thank you sir

I made it as much as I can. here it is...
Debug.zip
can you test and inform me?

Usage :
first create server
image
click to create server checkbox and select mqtt server adress then click connect

then open my app. go to settings and check your mqtt settings
image
you Use MAC tetting must be checked and server adress and port settings has to be match with server. then save
after saved connect your first device. after connection done open another app instance without closing first instance.
you should not need to change settings just connect to second device. after that you will see datas in server app.
Click view Datas button you will see your design in this page.
image
there are two combos on top of window. select one of device in this combobox and select other device in second combo box you will see readings in displays. I think you can do other stuffs yourself..
