https://devzone.nordicsemi.com/f/nordic-q-a/52592/unable-to-run-the-sample-application-code-ble_app_uart-on-bt832-moduleHello, I am currently working on BT840 and BT832 modules and trying to run the sample codes which are given by Nordic (specifically ble_app_uart which runs with UART service app provided by nordic). The application code on BT840 module is working asen-USTelligent Community 13Wed, 05 Aug 2020 19:57:31 GMThttps://devzone.nordicsemi.com/thread/263311?ContentTypeID=1Wed, 05 Aug 2020 19:57:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:557c3a88-48fd-4996-875d-6dae64b07e51Rafael<p>12 pF capacitors are needed when we add the crystal?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/211944?ContentTypeID=1Thu, 26 Sep 2019 05:21:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7a115317-23c4-4807-8bee-1160ea5beafbNikhilIngale<p>Hi Jorgen, Thank you for the quick response. Yes, i was doing the same mistake. It is working fine now by changing the clock source to internal one.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/211864?ContentTypeID=1Wed, 25 Sep 2019 13:56:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:10670455-4664-4e3b-91eb-8421fa247d4cJ&#248;rgen Holmefjord<p>Hi Nikhil,</p> <p>Have you connected a 32.768 kHz crystal to your BT832 module? From the datasheet, it seems like this is not included in the module but can be added on host board: &quot;For lower power consumption at idle state, a 32.768 kHz crystal is added on the host board.&quot;</p> <p>The examples in our SDK use the external crystal by default, as all our DKs are populated with this part. You can change the examples to use internal RC oscillator instead, by modifying sdk_config.h as described in <a href="https://devzone.nordicsemi.com/f/nordic-q-a/39655/programming-nrf52840-on-custom-board-with-the-ble_app_uart/153752#153752">this thread</a>.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
