Why can't nrf52810's broadcast name be displayed completely?

[liuyanfeng]

I add the MAC of acquisition device in the broadcast initialization of nrf52810 serial port routine, it can display complete. But I added the Mac to the template broadcast initialization of nrf52810. It cannot be displayed completely. Next, I will give two examples of broadcast initialization function code. thank you!

1 .

in ble_app_uart\pca10040e\s112, it is ok . it's name  "R Senior Watch01"

in ble_app_template\pca10040e\s112,

but ,it can't display  complete.

want to display complete ,only ,Unless noted。below

,why so  do ,it can only ？tell  me ,thank you very much!

Hello,

The name is truncated by ble_advdata_encode() if the payload is too big to fit inside the advertisment packet (31 octets), and it becomes too big as soon as you add the manufacturer field.

Best regards,

The same code, put in ble_ app_ UART / pc10040e / S112 is complete. And put it in ble_ app_ Template / pca10040e / S112 cannot be displayed completely. Only the

/ / init.advdata.uuids_ complete.uuid_ cnt = sizeof(m_ adv_ uuids) / sizeof(m_ adv_ uuids[0]);

/ / init.advdata.uuids_ complete.p_ uuids = m_ adv_ uuids;

If you leave out the comment, you can display it completely.

I don't know where the reason is, tell me, thank you!

The ble_app_uart example includes a scan response packet, which effectively double the available adv. payload from 31 to 62 bytes. For more details, please read the "scan response data" section of this tutorial: https://devzone.nordicsemi.com/nordic/short-range-guides/b/bluetooth-low-energy/posts/ble-advertising-a-beginners-tutorial
