BLE + ESB concurrent issue with no active BLE connectionhttps://devzone.nordicsemi.com/f/nordic-q-a/40227/ble-esb-concurrent-issue-with-no-active-ble-connectionHi, I&#39;m currently working on achieving BLE NUS + ESB UART concurrent implementation via timeslot API, by referring to the example here . I have ported it to utilize SDK15&#39;s ESB library, as well as the s140 SoftDevice via SES running on two nRF52840en-USTelligent Community 13Fri, 09 Nov 2018 09:36:32 GMTRE: BLE + ESB concurrent issue with no active BLE connectionhttps://devzone.nordicsemi.com/thread/156617?ContentTypeID=1Fri, 09 Nov 2018 09:36:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e63e25cd-bc1f-4a27-8295-7b7e13941d79Sigurd<p>Hi,</p> <p>I was not able to reproduce the isuse.
