Hi,
The system I have developed is based loosely on the Wisblock tracker example. In that, the green led is used to indicate transmission activity and the blue led just flashes continuously. The code that controls the green led is straightforward, but I cannot understand how the blue led is controlled - I’d like to use it for something else.
It could be the blue LED is setup as BLE indicator. In that case the blue LED blinks while BLE is active and goes on permanent when a phone connected over BLE.
The function to switch on/off the BLE blue LED function should be somewhere in the BLE initialization.
Search for Bluefruit.autoConnLed
// BLE LED function off
Bluefruit.autoConnLed(false);
// BLE LED function on
Bluefruit.autoConnLed(false);
Can you give me a link to the example code you are using?
It should be possible by just calling Bluefruit.autoConnLed(false); before you start advertising.
