How to get 1 or 2 meter NFC Communication ??
-
I have wristband(like smart watch) and another stationary device ,when the wristband reaches within 1 meter of the stationary device,stationary device want to show some indication for that i can use NFC communication? if yes how to get 1 meter NFC communication??

@mubassir-mk Why do you wanna use NFC. Does your wrist band have BLE? If yes, you can easily make this application with BLE.
Please watch this video

Hi @mubassir-mk, The NFC tag and reader can work only in Shorter working distance up to 10cm only. but Instead of that like @kowshik1729 suggested, you can try the BLE beacons since the BLE is active you need to power the device, but you can buy readymade beacons which can work with iBeacon or Eddystone protocols and it can work years using single coin cell battery.
Do you have any other particular reason to use the NFC?

@kowshik1729 Thank you....
Very help full your replay ... -
@mubassir-mk Glad that it helped.

Hi team,
Any one have experience in Altium schematic designing.
I am facing some issue in Hierarchy->harness in Schematic.
The offpage number for harness is not showing, and while generation the smart PDF if we click the harness port /green box the page want to go there automatically, but that also not working. -
Hi @dipu_varghese ,
Here is the sample input from the binary edge impulse inference,
Predictions (DSP: 16 ms., Classification: 1 ms., Anomaly: 2 ms.): idle: 0.91016 snake: 0.08203 updown: 0.00391 wave: 0.00391 anomaly score: -0.067”And from here for example we can try to get the updown values only by attaching the device to another controller and read the Serial string directly.
void setup() { // Start serial communication at 9600 baud Serial.begin(9600); } void loop() { // Wait until there is data available on the serial port while (!Serial.available()) { // Do nothing } // Read the input string from the serial port String inputString = Serial.readStringUntil('\n'); // Find the position of the "updown" value in the input string int updownPos = inputString.indexOf("updown:"); // If the "updown" value was found in the input string if (updownPos >= 0) { // Extract the "updown" value from the input string String updownString = inputString.substring(updownPos + 8, inputString.indexOf('\n', updownPos)); // Convert the "updown" value to a float float updownValue = updownString.toFloat(); // Output the "updown" value Serial.println(updownValue); } }The sketch should then output the "updown" value, which is 0.08203.
Hope this will be helpful, let me know if you need more clarification.
