Failed to send a packet larger than 20 bytes over BLEhttps://devzone.nordicsemi.com/f/nordic-q-a/89231/failed-to-send-a-packet-larger-than-20-bytes-over-bleHi, I tried to send a packet larger than 20 bytes by calling bt_nus_send on peripheral_uart but failed. After checked on DevZone, I found some similar problem and did the following changes: 1. Add some configs in pri.conf: 2. Calling bt_conn_le_data_len_updateen-USTelligent Community 13Thu, 23 Jun 2022 07:31:43 GMTRE: Failed to send a packet larger than 20 bytes over BLEhttps://devzone.nordicsemi.com/thread/373833?ContentTypeID=1Thu, 23 Jun 2022 07:31:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:038b331c-9552-4e7c-aad5-387796219145Joyop<p>Hi Vidar,</p> <p>Thanks for your reply.&nbsp;I&#39;ll look into this sample and come back with my progress.</p><div style="clear:both;"></div>RE: Failed to send a packet larger than 20 bytes over BLEhttps://devzone.nordicsemi.com/thread/373676?ContentTypeID=1Wed, 22 Jun 2022 12:00:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:98a8cf46-b685-4bf3-ae2d-8f045fba74e3Vidar Berg<p>Hello,</p> <p>Maybe you are trying to send the data too early since longer MTUs are negotiated after the connection is established. Could you please try the sample I posted here: &nbsp;<a href="https://devzone.nordicsemi.com/f/nordic-q-a/85258/comunicating-at-least-300-kbp-s-via-ble-nrf5340-with-android-phones">Comunicating at least 300 kbp/s via BLE nrf5340 with Android phones</a> ?</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
