Zoyi 703s application #59

Hi Kris... Ofcourse i remember :)

I purchase new multimeter with osciloscope functjon. This multimeter have usb c interface.

Propably this multimeter have nice uart data :) I foumd this on github. Open zoyi7p3s:

Master, please write simple app for comunicate via usb or add this multimeter to dmm bluetooth via usb conection. Please :)

can work on this device but it has to be a seperate app i think. because as its name Its for connecting bluetooth devices. Also It will make more complex that app. For these reasons I don't want to add it in Bluetooth DMM. But if the document is correct I can decode data. but I need time for it. so it can take long time.

i have unit 61e+ with bluetooth dongle. Works only with unit apk android.

I contact with unit for support pc app but i got answer no.

I ask on git hub some people for support unit 61e+ with bluetooth dongle but got answer ....this bluetooth comunication is hard to decode and unit use specify data transfer. I dreaming about unit 61e+ and your dmm bluetooth....with my youtube user. Now i only create live transmision on my channel. Video was stopped....

I already worked on uni-t devices but as you understand every uni-t device has its own decoding so I'm trying to figure out. There is multiple modes also combo display modes and e.g. I had to find every mode for every device. But as I working in some other job, I dont have so much time. But I will try to finish atleast 61e+ ;)

First of all can you try this F4 trick to see the uart data

ouchh look like you need uart to usb adapter for getting data and also not communucates over directly USB. The page that you send gets data from multimeterchipset to embeded mcu. so it looks like quite complicated task.

also you shoul look this video https://youtu.be/1MMvIY0CkR0?si=uG0u-xZkjLRZqLUo&t=10602

Ok, tommorow i try use putty and search some script to transfer output stable.
