I have my own 40 unity BLE Module in my room test. They&#39;re configured to advertise and broadcast iBeacon parameters every 100ms.

I&#39;m checking CRC code. Do you think that SPI communication could stop advertising ? Or is-it hardware problem ?</p><div style="clear:both;"></div>RE: nRF51822 stops advertising after few hourshttps://devzone.nordicsemi.com/thread/56149?ContentTypeID=1Fri, 24 Jun 2016 14:10:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6c06d93f-2983-4d48-a26c-0d63b80af856Anders Strand<p>I was thinking about the error codes returned by for example nrf_drv_spi_transfer().
