But this recent response to a customer feedback item suggests there is no support for a response yet.
ESP8266 FIRMWARE .INO MANUAL
But what about a return value? The text in the device template manual gives no clear answer.
We have successfully sent a command from cloud to device.
ESP8266 FIRMWARE .INO SERIAL
In the Serial monitor of the Arduino IDE you see the execution of the command: Once saved, we can send a command in the Device Explorer for our device: I added two separate input fields to this command. First, declare a new command in the device template: If you have a live connection with your device, you are able to send commands. And yes, you can even do C2D communication!Ĭheck out sending commands. Yes, this cheap device behaves just like an expensive device. You are now able to build fantastic dashboards for your devices, add some rules, etc. And that’s at a slower pace than sent to IoT Central by your device. IoT Central is using a throttle mechanism to protect its resources. Note: You will see new messages arriving every 10-15 seconds. Nice, not bad for a three dollars device. If everything goes well, you will see the arrival of telemetry very soon: Go to the IoT Central Device Explorer, select the ‘esp’ template and add a ‘real’ device:Īfter the creation, press the ‘Connect’ button to see the device credentials, needed for the sketch:Ĭopy these credentials into the sketch, compile it and deploy it to your ESP device. Once saved, you can register your device. Here I added a device template called ‘esp’ and I added two Telemetry items (as seen in the GitHub gist at line 69). So we need a Device Template for our device in IoT Central: Yes, IoT Central is expecting your device to be part of a group of devices, all with the same interaction. Ok, so you have a device, you have this sketch which can expose data to IoT Central but you need credentials for your device to communicate securely.Īnd to get credentials, you need to register your device first.Īnd to be able to register a device, you first need to tell IoT Central how you expect to interact with this kind of devices. You can try to compile it already but do not try to deploy it yet: the Device credentials are not set yet. You can already fill in the WIFI credentials: SSID and password.

ESP8266 FIRMWARE .INO CODE
LOG_ERROR("Sending message has failed with error code %d", errorCode) We just stick with one telemetry message with the two values in it: if (ms - lastTick > 5000) ", 10 + (rand() % 20), 1 + (rand() % 5)) ĮrrorCode = iotc_send_telemetry(context, msg, pos) The original code sends a message with one value and a ‘property’ (a special kind of telemetry message) one after the other (line 58-71). Simplify the message sent and set another interval I checked it out and I suggest two minor improvements:ġ. Microsoft provides a simple and straight-forward sketch:
Also, Do not forget to select the right serial port as seen device explorer: Only then you can select the NodeMCU 1.0 (ESP-12E) board. When the manual is referring to ‘additional board manager’, you first have to add the URL provided to the preferences of the Arduino IDE tool:Īfter that, in menu Tools | Board | Board Manager you can add the ESP board library:
ESP8266 FIRMWARE .INO HOW TO
In GitHub, you can find a very minimal manual on how to use the sketch provided. Also, check your USB cable it must be able to transport data.
ESP8266 FIRMWARE .INO PC
Note: if it doesn’t appear, restart your PC and try again. Please check if it’s recognized, it should appear in the Device manager: To program your ESP, attach it with a USB cable to your laptop. You can get an ESP8266 for less than three dollars so this is a fun and easy way to start using IoT Central. In this blog, we check how well the cheapest device is supported. If your device is not shown at the top of this list, you can fall back on HTTP only as long as your device is capable of executing REST calls. This repository is a great way if you want to start connecting with IoT Central with: These you find the source code for the devices shown above and several other devices. Luckily, Microsoft offers help in the form of a GitHub repository. IoT Central supports multiple devices at this moment if you start a new IoT Central application:īut what if you have other types of devices you want to connect?
