Hello,
i have a characteristic kept in user space with VLOC_USER. It has read/write with response props and has auth permissions set, both for read and write.
In the past i experienced weird behaviour because i was setting the update flag to 1 in the auth read reply.
Now I have tried the auth write request, and found that it always fails the reply with INVALID_PARAM error. Looks like this is caused by update flag set to 0.
According to the documentation on update flag:
If set, data supplied in p_data will be used to update the attribute value. Please note that for BLE_GATTS_OP_WRITE_REQ operations this bit must always be set, as the data to be written needs to be stored and later provided by the application.
Is it safe to use update=1 in reply params if characteristic value is kept in VLOC_USER?
Thank you
