GROW R503 fingerprint reader can't recognize fingeprints after waking up with error Timed out waiting for sensor wake-up

The problem

I've started using the R503 grow fingerprint sensor on a ESP32-ETH01 board, alongside some binary sensor for the door, the doorbell and the door lock.

I starded noticing that sometimes, when I touch the sensor, it doesn't recognize my fingerprint, not until it goes to sleep and then wakes up again.

[16:05:45][W][component:237]: Component fingerprint_grow took a long time for an operation (1032 ms).
[16:05:45][W][component:238]: Components should block for at most 30 ms.

I have configured the sensor as the doc says in order to use sleep mode. (However, I couldn't find a BC327 transistor, so I used a BC558)

These are the full logs: On these, the fingerprints recognizes my finger. Then, after going to sleep it does not. Afther another wake up, it works again.
