E_BLUETOOTH_ATT_INVALID_OFFSET

Long-value procedures depend on the current value length

E_BLUETOOTH_ATT_INVALID_OFFSET corresponds to ATT error 0x07. Offsets are used by Read Blob and prepare-write procedures to access a portion of an attribute value. The server rejects an offset that is beyond the value boundary or otherwise invalid for the selected operation.

A client can calculate a bad offset after assuming that every fragment has the same payload size, ignoring the first response length, or continuing a long read after the value changed. For writes, overlapping, skipped, or stale offsets can also reveal a broken fragmentation algorithm.

Reconstruct the fragment sequence

Log every offset and fragment length in order, together with the negotiated ATT MTU.
Stop a long read when a returned fragment is shorter than the maximum response payload.
Restart the procedure if the profile permits the value to change during transfer.
For queued writes, verify that offsets describe the intended final byte layout before Execute Write.
