https://devzone.nordicsemi.com/f/nordic-q-a/18786/nrf52-crc-ok-for-corrupt-packetsHello, I am seeing a strange problem with the nRF52 RADIO peripheral: sometimes a packet will be received that is corrupted, but the CRCSTATUS register indicates the CRC is OK. It seems like it&#39;s happening too often to be a coincidence where the corrupten-USTelligent Community 13Fri, 06 Jan 2017 15:14:31 GMThttps://devzone.nordicsemi.com/thread/72565?ContentTypeID=1Fri, 06 Jan 2017 15:14:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:690ae429-5c90-4ceb-ba65-4e2a890ca652ovrebekk<p>Hi Paolo</p> <p>I doubt very strongly this is a hardware issue. It sounds more like an issue with the ESB library or the application code.</p> <p>Do you have any other peripherals in the system using DMA?</p> <p>Do you have any peripherals generating interrupts?<br /> If so, have you set the interrupt priority to something other than 0? The ESB library might misbehave if it gets interrupted when inside the radio interrupt.</p> <p>Do you know how much of the RAM is being used?<br /> If the CRC is OK but the packet is not, I am tempted to think that some other peripheral or the MCU is overwriting the RAM used by the ESB library.</p> <p>Best regards Torbjørn</p><div style="clear:both;"></div>
