Hi I know almost next to nothing about ECE...but I have gotten a question about a missing component in my network idea. Would be great if someone can point me to a good direction.

So basically I want my device to able to communicate with my back-end server. The route is as follow...

Device (made by supplier, with on board MCU)

||

? (what is this missing component?)

||

Chip (wifi / BLT module)

||

router

||

cloud

||

back end Server

Thank you so much...

 

device-wifi chip-router-back end server

if this done over the internet, you can add dsl/cable modem between router and server.

you can also stick wifi access point (ap) in there if you want to deferentiate wife functionality from router functionality. that is actually interesting topic in itself from logistical point. so you would have:
device-wifi chip-wifi ap-router-back end server

an example can be:
arduino uno is device (no native network connectivity)-esp8266 provides wifi connectivity for uno-home lan router with wifi ap (whatever your isp provided you)-server on your home lan

 

Thanks for the answer. What about the linkage between the MCU and the wifi chip ?

That thing is more like an adapter that I will need to convert whatever I can retrieve from the the device MCU to something meaningful through the broadcasting chip.

Lets say some analogue signal I will be retrieving from the MCU, but those need to be interpreted before broadcast, and that's what the missing component should do. What should it be?

That is easy. I can even give u example that I actually used.

Tmp36 analog temperature sensor to uno adc. Uno digitizes and records the analog signal from temp sensor. Uno also interprets the temp reading. Then uno sends it to WiFi device. I used esp8266 for WiFi device. But u can use uno specific WiFi device that plugs directly onto uno board.

When I saw u using cloud. I was wondering if u r mixing software and hardware in your chain. The missing piece u are looking for is software called firmware. Firmware is basically software that runs on micro controller
