Bonjour,
je viens d'acquérir un microteleinfo v2 et impossible d'avoir des trames.

Le context :
-le compteur EDF : Sagem
-un RPi 3 avec Raspian Jessie à jour et fresh Install
-en wifi + ssh server + install picocom
-les configurations effectuées sont :
dans /boot/config : enable_uart=1
dans /boot/config : dtoverlay=pi3-disable-bt + systemctl disable hciuart
dans RasPi-config : interfacing options/P6 Serial/login Shell accessible over serial : No et serial port hardware enable : Yes

/var/log/messages donne :

Terminal ready

La LED verte est bien allumée et fixe.
La LED rouge clignote lentement.

Merci
