https://devzone.nordicsemi.com/f/nordic-q-a/88077/nrf52832-spi-freertos-problemHi, I am developing nRF52832, ADS1291. I got the data from ADS1291 normally through SPI communication. And I applied RTOS by referring to the nRF5_SDK_17.0.0/examples/peripheral/blinky_freertos. It seemed to work normally, but while receiving dataen-USTelligent Community 13Fri, 27 May 2022 02:38:19 GMThttps://devzone.nordicsemi.com/thread/369696?ContentTypeID=1Fri, 27 May 2022 02:38:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d4dd0509-2cce-49d9-9d0b-a51da1c384d2Minseo<p>Hi.</p> <p>Thank you.

Maybe connect a logic analyzer trace to check how frequently you are calling spim and how the&nbsp;interval is affected by BLE.</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/368542?ContentTypeID=1Thu, 19 May 2022 08:48:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ffc8ab4f-b4f8-4ac4-907d-ccfcdd2fa115Minseo<p>Hi.</p> <p>I just checked.</p> <p>It works because I&#39;m turning off the BLE</p> <p>What does RTOS have to do with BLE?</p> <p>Thank you.</p><div style="clear:both;"></div>
