https://devzone.nordicsemi.com/f/nordic-q-a/8687/sending-hexadecimal-values-to-my-ble-devicei used this function to send data to my ble device ble_nus_string_send.this function sends ASCII values. and when i pass this function hex values it converts them into ascii and then sends. But it terminates data when i pass 0x00 and for some other hexen-USTelligent Community 13Wed, 02 Sep 2015 12:13:48 GMThttps://devzone.nordicsemi.com/thread/31852?ContentTypeID=1Wed, 02 Sep 2015 12:13:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:42a151a3-da78-43bb-8cec-2bf81b97dd07Spirit<p>Nomi, did you solve the problem?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/31854?ContentTypeID=1Wed, 12 Aug 2015 16:34:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8491add5-3cad-4618-b164-53096ceadcadNomi<p>I am using an ios app nRF Toolbox</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/31853?ContentTypeID=1Wed, 12 Aug 2015 11:58:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fe679ec0-f56e-4fc0-b52f-64ea4a653eb8Anders Strand<p>Hi Nomi!</p> <p>I am assuming that you are using the ble_app_uart example. The conversion to ASCII does not happen inside the ble_nus_string_send(ble_nus_t * p_nus, uint8_t * p_string, uint16_t length) function. It simply treats the p_string variable as a byte array, and does not care what it contains (value wise).</p> <p>The issue is probably that your receiver device treats this byte array as a ASCII string, and for example terminates on a 0x00 value.</p> <ol> <li>What is the receiver device?</li> <li>Are you writing the receiving software yourself, or using a premade application?</li> </ol><div style="clear:both;"></div>
