NRF52840 SoftDevice S140 6.1

[Stefan B]

Hello,

I got a problem duringing advertising with the following scenario:

1. I advertise some data to a Scanner.
2. The Scanner answers with a Scan Request.
3. The ble event handler jumps into BLE_GAP_EVT_SCAN_REQ_REPORT
4. within this event, I  change the scan response data depending on the received peer address.

--> That  data is not sent in the scan response packet.

Obiviously I can not change the response data until the current advertising has been terminated.

Is this a bug in the Softdevice or done on perpose ?

Best regards

Stefan

PS: could you help me finding the ble timing parameters (timing between advertsinng --> scan request --> scan repsonse) within the bluetooth spec ?

Hello, I want to clarify:

1. The bluetooth spec foresees an inter frame space T_IFS of 150µs before the scan response packet must be sent.
2. Thus, it should be enought time to make some changes in the response data field ?!

Best regards

Stefan
