S130 v2.0.0-8 ble_gattc_evt_write_rsp_t wrong data??

[Marius Heil]

Hello,

I was just editing the handling of sent packets and I wanted to evaluate the contents of the ble_gattc_evt_write_rsp_t struct which is part of the BLE_GATTC_EVT_WRITE_RSP i suppose. When I receive the event, I check the contents of bleEvent->evt.gattc_evt.params.write_rsp.data.

Data length is always reported as 0 for me and the data[] does not contain any valid data,... However on the client side I receive everything correctly. What does that mean? How is this event supposed to work?

I doubt you get the data back for a normal write because for a normal write the bluetooth-level response is just a response code and nothing else. I would expect to see that data filled in only for long and reliable writes where the data is sent back from the server as part of the reply.

.. and the message sequence charts in the documentation seem to suggest that is what happens also.
