Right.

Mmelta101 UPI uses UPI ID(which are most often QR code) to xfer money

Marvin•11/20/24, 9:31 AM

So in order to make a payment, a merchant will scan my UPI QR? Or I scan theirs?

melta101OP•11/20/24, 9:32 AM

we scan thier

melta101OP•11/20/24, 9:33 AM

they can request money also from us by scanning

melta101OP•11/20/24, 9:34 AM

now a days
everthing is done with UPI
from elec bill, house rent/maintaince, daily groceries, online commerce etc

Marvin•11/20/24, 9:35 AM

do you have to explicitly move money from the bank to it. Or just link the bank to it for automatic movement?

Umesh Lokhande•11/20/24, 5:49 PM

It's a good solution to implement Zigbee but I'm using XBee even before stm32wb launched. I stick with Digi because of the complete suit offered by Digi like XCTU Software and other aspects like the wide user community around Xbee

Umesh Lokhande•11/20/24, 5:58 PM

It's easier to handle Xbee configuration using XCTU and then use it with high-level programming language. I never had enough time to do everything by my own given tight deadlines to build applications using Zigbee that's why I suggest using Digi's XBee solution

It is not standard. Header files,

.c

for definitions.

So iam using python to handdle the data coming from ethernet
And i wanna use python like backend and electron js front end to make profession interface..

In case you're planning to use Python with Flask micro web framework to handle backend and ElectronJS for the front end. Then maybe this video will guide you through https://www.youtube.com/watch?v=627VBkAhKTc Hope it may help. Best wishes!

Hi everyone, I want to build an induction heater, and it requires a high current power supply, like 50A, how can I get that for a cheap price? Does anyone worked on this before?

Q_i99•11/22/24, 10:52 AM

I am currently working on a personal project where I have serveral iot devices which have several sensors attached. However, I am not quite sure about the best way to design the communication flow. Specifically, I need both real-time data and historical data.

Initially, I thought about having an MQTT broker for communication between my iot devices and backend (django) and then through my backend I can use websockets to forward real-time updates to my mobile app and http for historical data. However, I’m unsure if this is the most efficient approach or if I should consider having the mobile app directly communicate with the MQTT broker for real-time data.

Umesh Lokhande•11/22/24, 12:49 PM

The use of MQTT broker between the iot devices and backend server will be fine. But I don't think many people in the industry uses Django. I'd prefer to go with MERN Stack if not MEAN. And just to add, if you choose to use NodeJS as backend then I suggest to install dedicated database like MongoDB to store data and then send any where (in realtime).

Hey @Event Pings and @MCU, MPU & Firmware,
We've been working on a couple of things for Advent of Code next month we want to share with you in today's Office Hours. Teaser: We hope you'll be able to do examples from EH sessions on the target hardware from wherever you are. But we'd also like your input/feedback to make this tool as useful as possible for everyone!
