CDC ACM UART ISR not triggered during ESB connectionhttps://devzone.nordicsemi.com/f/nordic-q-a/91227/cdc-acm-uart-isr-not-triggered-during-esb-connectionI am trying to port some code I wrote for Gazell, which I guess acts more elegant since it uses PPI, a workqueue, timeslots, etc. I have an ESB connection in which I receive data in every packet. I am trying to enable tx interrupts in ESB_EVENT_RX_RECEIVEen-USTelligent Community 13Tue, 23 Aug 2022 02:26:44 GMTRE: CDC ACM UART ISR not triggered during ESB connectionhttps://devzone.nordicsemi.com/thread/382788?ContentTypeID=1Tue, 23 Aug 2022 02:26:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e9308fa5-d996-454e-9648-620fad93a8c5Abraham Hamidi<p>The problem&nbsp;was that my data was malformed. I&nbsp;figured this out by sending test data. I was using memcpy the wrong way for my custom data and resolved the problem. ISR&#39;s were always working fine. As for the memory management exception, I found out that zephyr ring buffers don&#39;t include concurrency.</p><div style="clear:both;"></div>
