https://devzone.nordicsemi.com/f/nordic-q-a/23149/transfer-stops-for-a-few-secondsHello! We have built an app that transfers files from an app on Android to the device running an nRF52 with S132. On the device is an external flash using SPIFFS as a file system. We run an RTOS, but the BLE has highest priority.

We have not solved problem yet. It is still there, but it seems to depend on telephone, connection, etc. No idea. But we have anyhow moved on, the problem is not so pronounced any more, since we managed to increase the transfer speed significantly.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/91050?ContentTypeID=1Tue, 08 Aug 2017 07:20:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:aee6e5b4-c5c7-4a5a-87cb-cd373bd6b8ffSusheel Nuguru<p>sorry for very late reply. Most probably you have solved this problem, If not, It is very hard to say what caused the problem without knowing more about your project. Which RTOS are you using?</p><div style="clear:both;"></div>
