https://devzone.nordicsemi.com/f/nordic-q-a/2156/nrf8002-output-pins-accessed-from-iphone-androidI am building a new PCB board for a prototype. It will be used for proximity. It will blink on low battery. It also has a piezo speaker attached to a pin as well. My question is this. Can I have a button in the app call the speaker to buzz or a buttonen-USTelligent Community 13Wed, 09 Apr 2014 13:58:18 GMThttps://devzone.nordicsemi.com/thread/9145?ContentTypeID=1Wed, 09 Apr 2014 13:58:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b22444eb-4802-4d0f-8653-deb3188480d8Stavros Tsardounis<p>Thank you for your response. My question is though. Can I use a button from an application to trigger the LEDs or buzzer? If I want to find the location of the chip, can I call an action from my phone to find it?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/9144?ContentTypeID=1Wed, 09 Apr 2014 12:23:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c835b260-9a7b-482c-a63f-c432cad74a86run_ar<p>Hi,</p> <p>You can trigger a buzzer or LED if you configure the Proximity - Immediate Alert characteristic and writes to this from the Phone. I would recommend downloading nRFgo studio to take a closer look at the possible configurations. The nRF8002 is were simple to use, so it might not suite all applications. If you need more advanced functions consider using the nRF51 series or the nRF8001 connectivity chip.</p> <p>Br,</p><div style="clear:both;"></div>
