Sending more than 13 bytes payload in adv packet causes BUFFER_OVERFLOW. #267

I'm using the BLE_GAPButton example and trying to send 15 packets in the advertisement payload. Contents of adv packet are: default flags, device name (5 chars), local service list along with 15 packets of data. However, I get the following buffer_overflow error when using on a Laird BL654 module (based on nRF52840).

DEVICE MAC ADDRESS: de:4b:ed:17:be:63
Button Count = 0
Error code = 1
Updating payload failed: BLE_ERROR_BUFFER_OVERFLOW: The requested action would cause a buffer overflow and has been aborted
Button Count = 1
Error code = 1
Updating payload failed: BLE_ERROR_BUFFER_OVERFLOW: The requested action would cause a buffer overflow and has been aborted

@pan- has kindly already fixed the issue locally (since we were blocked for a customer demo tomorrow). Thank you @pan- . The patch is attached below: data-builder.zip

Currently, I'm not advertising the local service list & for now, that's a compromise that is OK to make.
