Hi guys, thanks for the great documentation!!

I was going through your lighting_with_state.ino sketch and saw that you check for data credits before you call setLocalData. I'm a little confused since per the Nordic docs (page 77 of the nRF8001 product spec), setLocalData doesn't use up any data credits but calling sendData does.

What was the reason you check for available credits before you set the local value?

For reference (lighting_with_state.ino, lines 164 - 176):

  // STATE
  if (nrf->isPipeOpen(BUTTON_STATE_PIPE) && nrf->creditsAvailable()) {
     Serial.println("Setting 1");
     foo = 1;
     nrf->setLocalData(BUTTON_STATE_PIPE, 1, &foo);
  } 

  // TX
  if ( nrf->isPipeOpen(BUTTON_TX_PIPE) ) {
     Serial.println("Sending 1");
     foo = 1;
     nrf->sendData(BUTTON_TX_PIPE, 1, &foo);
  }

Thanks!!

The maximum "characteristic" length in BLE is not 20 bytes. It is 512 bytes. I think you're confusing the standard MTU which is typically 20 bytes.

Hello there,
I am following your tutorial for the PlayOn on OSX but I am getting this error when is installing the Segger JLInk.

Did you encounter this issue before? I am on OSX El Captain and tried both the old version you suggested and the new release of the NRf Go studio but still the same issue.
