Bonjour,

## Mon problème

Hello !

Je rencontre un soucis sur l’integration du lecteur d’empreinte digital GROW 503 ([lien AliExpress](https://fr.aliexpress.com/item/33053655412.html?spm=a2g0o.productlist.main.1.5b7f3c4f42tz20&algo_pvid=f2104332-3de0-431b-879e-7246c2c6f04d&algo_exp_id=f2104332-3de0-431b-879e-7246c2c6f04d-0&pdp_npi=4%40dis%21EUR%2116.07%2115.27%21%21%2117.04%2116.19%21%40212bfd8c17221230129334542e70ed%2112000035347679713%21sea%21FR%210%21ABX&curPageLogUid=YPdCWECUkElG&utparam-url=scene%3Asearch%7Cquery_from%3A))

Après l’avoir intégré dans ESPHOME, cablé ([comme mentionné dans la doc esphome](https://esphome.io/components/fingerprint_grow.html)), mis en route, j’ai l’ESP32 qui reboot à chaque fois que le capteur lis une empreinte.

Les logs me retournent un «&nbsp;CORRUPTED&nbsp;». J’ai essayé de débrancher le bus UART pour vérifier et c’est bien la connection UART au lecteur d’empreinte qui provoque ce redémarrage.

J’ai test plusieurs ESP32 (USB-C / Micro USB / Nodemcu v2) et à chaque fois j’ai la même reaction.

J’ai posté une issue sur le github Esphome ([GROW R503 Fingerprint reader keep restarting once I scan a finger · Issue #6095 · esphome/issues · GitHub](https://github.com/esphome/issues/issues/6095))

J’ai l’impression que ça vient de la compilation du firmware?

Quelqu’un a une idée?

Merci a vous !
