what is the communication protocol used in Bluetooth module HC-05 & HC-06, wich version is better for sending and receiving information between a mobile phone and arduino

Edge computing provides the following benefits:

Real-time local data processing enables immediate actions even without connectivity with the backend system.
Pre-processing and analyzing data before sending it to the backend system to reduce the payload size and communication frequency (resulting in lower cost and potential battery saving).
In case of connectivity issues, the device can locally store messages and transmit them once it is back online (you won't lose telemetry data during a network outage).

You might find my article interesting as it partially covers this topic.

Gateway vs. Gateway-less Industrial IoT considerations

Introduction In this post, I will describe two approaches to the Industrial Internet of Things deployments and provide my perspective. Hopefully, it will help you choose the proper architecture for your specific case.
Before we start, I will briefly define the Edge Gateway.
Definition of the Edge Gateway Edge Gateway is a computer located inside...

You can use Serial UART to communicate HC-05/06 with other devices like MCU. If you want to use device as master as well as slave then go for HC-05. If only slave is good enough for your use case then HC-06 will do the job.

techielew•2/20/24, 4:46 AM

From DH22 page: "Compared to the DHT11, this sensor is more precise, more accurate, and works in a bigger range of temperature/humidity, but it's larger and more expensive."

https://www.adafruit.com/product/385

DHT22 temperature-humidity sensor + extras

The DHT22 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on ...

Ttechielew arent both discontinued?

Umesh Lokhande•2/20/24, 4:59 AM

Yes. Still, both DHT11/DHT22 are widely popular and available across local retailers

Ttechielew Why the requirement for no ROS?

wafa_ath•2/20/24, 8:35 AM

Nao robot doesn't support ROS due to differences in communication protocols and software architecture

Umesh Lokhande•2/20/24, 4:22 PM

To create ui you don't need IBM Watson. I have just shown it as an example. You only have to install node-red-contrib-ui from Palette Manager. As shown in the video. To control RPi from other device can also be done locally as shown in the video. But you can pretty much use any other free cloud service
