Make sure the&nbsp;NRF_SDH_BLE_GATT_MAX_MTU_SIZE is configured to match with at least bigger than the size of the characteristic (by default max MTU is 247 bytes) and the connection parameter negotiation (NRF_BLE_GATT_EVT_ATT_MTU_UPDATED event) actually set the MTU to what expected.&nbsp;</p><div style="clear:both;"></div>
