I want to connect Blynk with Microbit, I find the temperature interface from http://docs.blynk.cc/ but I can’t find it from Blynk App, my Blynk App is version 2.23.1, please advise how I can get the Microbit temperature.
More along the lines of “it may work with some examples out in the wild (AKA not in active Blynk example files) but is uncommon and or old hardware thus is acknowledged, but not being actively developed on.”
That setting is primarily used to show the pin designations for using digital pins in the widget settings.
But when using virtual pins you could actually run code on a UNO even if the App “thinks” it is a Raspberry Pi… in other words doesn’t really matter outside of its specific intent.
Thanks for your information, may I know whether we can code at Arduino instead of Microbit? How can I get the information from Microbit itself sensor when I create the Blynk?
you can install the Adafruit Micro:Bit library which then gives you a temperature_data_get() method to read the internal Micro:bit temp sensor.
Note that it says “It’s not precise at all but it does go up when it gets hotter and down when it gets cooler”.
Also, the example shows how to upload the data to AdafruitIO and uses a delay(5000) which isn’t the way to do it if you’re trying to use Blynk instead.
For Microbit, the SoftDevice should be nRF51 but no idea S110 or S130 should be selected.
Under Flashing a SoftDevice point 7, which one is better? Point 8, I can’t find the Tools -> nRF5 Flash SoftDevice from Arduino IDE, my Arduino IDE is 1.8.3.
Is there any drawback after flashing the board if I need to code the Microbit with Block code again? Can I backup existing board before I flash?
Hope you can instruct me a bit to this. Many thanks.
