problem on FATFS (SDCARD) and BLEhttps://devzone.nordicsemi.com/f/nordic-q-a/28929/problem-on-fatfs-sdcard-and-bleHello everyone I am trying to write to SDCARD with FATFS. Data received from BLE and SAADC incoming data. Writes every second. The size is about 100 bytes. SAADC is 1000 samples per second. When BLE communication is stopped, normal data is writtenen-USTelligent Community 13Fri, 05 Jan 2018 14:01:59 GMTRE: problem on FATFS (SDCARD) and BLEhttps://devzone.nordicsemi.com/thread/114465?ContentTypeID=1Fri, 05 Jan 2018 14:01:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:08ed07aa-2b2e-4300-975e-c182ff2bcb6asfujimoto<p>m sorry. There was a bug in BLE. There was another signal on the CS pin of SDCARD. I apologize to you for a fuss over.</p><div style="clear:both;"></div>RE: problem on FATFS (SDCARD) and BLEhttps://devzone.nordicsemi.com/thread/114464?ContentTypeID=1Thu, 04 Jan 2018 12:20:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:03e7f4af-fda8-477c-897c-31b3262007a0J&#248;rgen Holmefjord<p>What do you mean by <em>&quot;the data will collapse&quot;</em>? Could you post some code snippets showing how you setup FATFS and how you write to the SD-card? Are you checking that there is no error codes returned from function calls?</p><div style="clear:both;"></div>
