https://devzone.nordicsemi.com/f/nordic-q-a/62185/assigning-manufacturing-data-to-advertisement-truncates-the-device-nameHello, we are creating a device on an nRF52832. I started our project based on the examples/ble_peripheral/ble_app_uart project, which worked fine. However, I needed to modify the advertisement data, so I tried to merge in some code from the ble_app_beaconen-USTelligent Community 13Fri, 05 Jun 2020 09:42:37 GMThttps://devzone.nordicsemi.com/thread/253473?ContentTypeID=1Fri, 05 Jun 2020 09:42:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:75799951-5829-4c61-b8ce-260b20e67364Karl Ylvisaker<p>Hello,<br /><br />I suspect that you have exceeded the 31 byte advertisement length limit, which is why your name is being cut short.<br />Be advised that each new data field comes with two bytes overhead - one to indicate length, and one to indicate type.<br />Alternatively, you could also use the SHORTENED name option, to maximally allocate 6 bytes to device name.<br />Could you verify that the contents of your advertisements does not exceed 31 bytes in total, when the device name is cut short?<br /><br />Additionally, are you familiar with using the <a href="https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Sniffer-for-Bluetooth-LE">nRF Sniffer tool</a>? It is a powerful tool to wield when developing BLE applications, and would allow you to see the contents of the advertisements your device is transmitting, as they appear to other devices.<br /><br />Best regards,<br />Karl<br /><br /><br /></p><div style="clear:both;"></div>
