Bluetooth Power Monitor
So I've discovered the power of EAGLE cad software and oh my goodness, this is amazing! I will have a fantastic looking prototype!

^ the drawing looks great :up:

Thanks, here's the first Rev. 00 I've submitted for printing! I'm very excited! :D
Bluetooth Power Monitor

Asudem:
Perhaps I might receive better feedback here over the official support forums: I have made a little program to test the logic of the microcontroller of the device.

In many examples created by the manufacturer, to wait for a bluetooth connection in the setup() routine, the following code is used:

--- ---  /* Wait for connection */
  while (! ble.isConnected()) {
    delay(500);
  }And it works correctly. However calling this from within the loop() method yields.... interesting results.


The logic of the Feather's microcontroller is tested in 4 ways:
If the bluetooth module is not connected, it should return false.

--- ---  if (!ble.isConnected())
  {
    printBoth(F("True"));
  }
  else
  {
    printBoth(F("False"));
  }If the bluetooth module's connected status is false, it should return false.

--- ---  if (ble.isConnected() == false)
  {
    printBoth(F("True"));
  }
  else
  {
    printBoth(F("False"));
  }If the bluetooth module is not connected or if the bluetooth module is not connected, it should return false.

--- ---  if (!ble.isConnected() || !ble.isConnected())
  {
    printBoth(F("True"));
  }
  else
  {
    printBoth(F("False"));
  }If the bluetooth module is connected, it should return 1.

--- ---printBoth(String(ble.isConnected()));Where "printBoth" is simply a function which outputs the string to both the Serial and bluetooth for display. If I run the program with an incremental timer, here are the results:
Test#, Delay in Seconds, Test 1 results, Test 2 results, Test 3 results, Test 4 results

* 0, True, True, True, 0
* 1, False, True, True, 0
* 2, False, True, True, 0
* 3, False, True, True, 0
* 4, False, True, True, 0
* 4, False, True, False, 0
So, I thought that was strange, but check this out....


* 4, False, True, False, 0
* 4, False, True, False, 0
* 4, False, True, False, 0
* 4, False, True, True, 0
* 4, False, True, False, 0
* 4, False, True, False, 0
So yeah, I don't know what's going on, but I don't know what to believe anymore...

Stoic Joker:

--- Code: C# ---if (!ble.isConnected())  {    printBoth(F("True"));  }  else  {    printBoth(F("False"));  }


...Okay, am I completely off my nut...or does this really read as:

If it's true, that connection is false, print true?? ...I don't think the '!' is helping the output's clarity any.

I know nothing about the BT controller you're working with, but that code just strikes me as painfully confusing to work with.
