emg sensor with esp32
Currently, I am working on a project to transfer data from an EMG sensor using an ESP32 to a computer wirelessly. I will use the Wi-Fi available on the ESP32. I have three ESPs, two of which will be used as slaves and one as a master to collect data from them. Then, I will send this data to the computer.
Additionally, after receiving this data on the computer, I can process and display it in Excel or plot it
I think this is long and unprofessional way to do it ... Am i right... And can u segest other ways to do so...
Solution:
@wafa_ath
Use ESP-NOW protocol for fast and low-latency communication between the ESP32s, One ESP32 can act as the master to collect data from the other two and then send the collected data to the computer over, then Implement a TCP or UDP server on the computer and have the master ESP32 send the collected data directly to the server....
esp32 on a VPN
I am trying to connect esp32 as a VPN client . Anybody has done that before?
Solution:
it's great that u successfully done it with openwrt , and using openvpn IoT Devices is a great way to securely manage and access them remotely , can u specify the iot devices that u are using (whether they have the capability to run an OpenVPN client or support VPN connections)

between mqtt and Coap
Hello #edge-networking am developing a smart automation system for factory The system needs to collect large data from sensors ( temperature, humidity, motion, door/window status) and control actuators (lights, thermostats, locks). And the system needs to be very secure. When i was doing my research i stopped between MQTT and CoAP protocols, what do u think is the best one for this project

How to Transmit Sensor Data Between Arduinos Over Long Distances with Minimal Power Consumption?
I would like to send values from an Arduino to another one (one value every 10 minutes). I have a distance of 80-100m outdoors with trees between the Arduinos. The transmitter should consume as little power as possible because it will be on battery, while the receiver will be on mains power.
What solution do you suggest? I don’t know the maximum distance (WiFi, radio, Bluetooth, IR…).
Thanks...
Solution:
Another option is Bluetooth with Coded PHY support. This extends the range of bluetooth and is likely the lowest cost and power. LoRa is a good option as well, but your receiver has to function as a gateway. LoRa will have the best range, but BT coded PHY should meet or exceed your range needs as well. As always with wireless range, I would do some field testing with existing product or dev kits before finalizing your design. Also, antenna design/performance is always a large factor with any...
RFID
what kind of technology that is used to identify and track objects that can replace RFID technology?
Solution:
This is a big topic, there are a number of technologies that are evolving to address indoor location/tracking, but they all have their own unique properties. Bluetooth is adding features such as time-of-flight and HADM (now called channel sounding). Those are worth reading up on. Also Ultra Wide Band (UWB) is another technology targeting location/tracking applications. Cost, power, range, accuracy and infrastructure requirements are all factors to consider.

Ask a Developer: Understanding MQTT Topic Structures
MQTT is one of the most popular IoT communications protocols for wireless sensor networks. Its publish-subscribe architecture can streamline, simplify, and scale the creation and provisioning of potentially massive edge networks—if you structure the pubsub technology appropriately from the start.
In his time at AWS IoT, consultant and DevHeads cloud and networking expert Lukasz Malinowski gained a mountain of experience working with large-scale IoT deployments. He also and learned how to build MQTT networks for extensibility from the ground up.
On this DevHeads Demo, Lukasz outlines key concepts for understanding and properly structuring MQTT topics in a Roblox environment to explain what it takes to ensure the success of your IoT deployment long term. Jump in and see for yourself....
