Is there any flow control in L2CAP in s110, nrf51?https://devzone.nordicsemi.com/f/nordic-q-a/12164/is-there-any-flow-control-in-l2cap-in-s110-nrf51I have to implement high throughput and I plan to use L2CAP. My transmission has to be reliable so I need flow control functionality. In API, I can only see functions for CID managing and sending data but according to BLE specification Link Layer anden-USTelligent Community 13Mon, 02 May 2016 13:02:00 GMTRE: Is there any flow control in L2CAP in s110, nrf51?https://devzone.nordicsemi.com/thread/46038?ContentTypeID=1Mon, 02 May 2016 13:02:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b77d7013-a15a-4020-975a-c764a84b403aDavid Edwin<p>The TX_COMPLETE event can be used as a method of flow control. Each transmit/send using the L2CAP API should trigger a TX_COMPLETE.</p> <p><a href="https://devzone.nordicsemi.com/question/2540/understanding-ble_evt_tx_complete/">https://devzone.nordicsemi.com/question/2540/understanding-ble_evt_tx_complete/</a></p><div style="clear:both;"></div>RE: Is there any flow control in L2CAP in s110, nrf51?https://devzone.nordicsemi.com/thread/46037?ContentTypeID=1Fri, 26 Feb 2016 12:36:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fb539552-fdb5-4270-833c-1995c399a4ddAl Bundy<p>Well, to start I just need to know if there is some kind of flow control and error correction in lower layers implemented in s110 for nrf51.</p><div style="clear:both;"></div>RE: Is there any flow control in L2CAP in s110, nrf51?https://devzone.nordicsemi.com/thread/46036?ContentTypeID=1Fri, 26 Feb 2016 12:24:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c7a57141-43cf-4771-8f15-c482618849c5Wojtek<p>I would really like to know if you will succeed with that concept - I hope you will post some results when you get them :)</p><div style="clear:both;"></div>RE: Is there any flow control in L2CAP in s110, nrf51?https://devzone.nordicsemi.com/thread/46035?ContentTypeID=1Fri, 26 Feb 2016 12:18:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bf1f76d6-b110-4506-92bc-eddf3176e33fAl Bundy<p>The higher the better, now I got 9 minutes long transmission using GATT, I transmit data from mobile phone to nrf51422, connection interval is 40 due to mobile. There is BLE_L2CAP_EVT_RX event in ble_l2cap.h.</p><div style="clear:both;"></div>RE: Is there any flow control in L2CAP in s110, nrf51?https://devzone.nordicsemi.com/thread/46034?ContentTypeID=1Fri, 26 Feb 2016 11:51:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:02bb9b6e-653e-46da-976c-47298876300fWojtek<p>What throughput do you need? What receiver are you planning to use? Current softdevices only allow l2cap tx, no rx AFAIK.</p><div style="clear:both;"></div>
