loss of characters in advertising name in sdk 15.3

[Rohit]

Hello All,

I am working on the nrf52810 module.

I am using sdk 15.3 with softdevice 6.1.1. (IDE segger)

Issue- 

1. I am giving the Advertising name as " TEST_01 "

But if i load program to board and powered up then it is showing  "  TEST_ " only.

not whole name as i have given( loss of "01" ).

So what i have modified to solve this issue.

2. Please check below code of "ble_advtdata.c"

                                  if (((p_advdata->name_type == BLE_ADVDATA_FULL_NAME) ||
                                                          (actual_length <= p_advdata->short_name_len)) &&
                                                          (actual_length <= rem_adv_data_len))
                                  {
                                   // Complete device name can fit, setting Complete Name in Adv Data.
                                   adv_data_format = BLE_GAP_AD_TYPE_COMPLETE_LOCAL_NAME;
                                  }

I have changed to 

if ((p_advdata->name_type == BLE_ADVDATA_FULL_NAME) && (actual_length <= rem_adv_data_len))
{

// Complete device name can fit, setting Complete Name in Adv Data.
                                   adv_data_format = BLE_GAP_AD_TYPE_COMPLETE_LOCAL_NAME;
 }

After changing also facing same issue.

Please help for solving this issue.

Regards,

Rohit

Hi Rohit. 

The advertising name will automatically be cut when there isn't any room for the whole name in the advertising packet. 

Remember that you can only fit 31 bytes of data in the advertising packet. If you try to remove some data from the advertising packet, you should be able to see the entire name advertised. 

Cheers, 
Joakim

Thanks for your response.

But i have tried with short name like " TEST_01 ".

and it is only 7 characters so it should show/advertise with whole name.

Then what is the modification ?

Waiting for your reply.

Regards,

Rohit

Is the name the only data in your advertisement packet?
Or are you advertising some UUID, manufacturer spec. data or something similar? 

The total size of the advertising packet can only be 31 bytes.
The first thing to get cut if the advertising packet is full, is the advertising name.
