+# Remise au goût du jour le petit script luatool.py
+
+## Sources
+https://github.com/4refr0nt/luatool
+
+
+## Description
+Le petit script python *luatool.py* permet d'automatiser le téléchargement de
+scripts *.lua* sur un NodeMCU branché sur le port USB.<br>
+Mais il permet aussi et surtout de le faire via WIFI. Pour cela il faut que le petit serveur *telnet* tourne sur le NodeMCU !
+
+
+## Problématiques
+La version actuelle datant de juillet 2017 ne fonctionne plus avec les nouveaux firmwares de NodeMCU. Il a y un problème au moment de l'initialisation de la connexion série.
+
+
+## Travail effectué
+* J'ai donc repris le code python et juste après l'initialisation du port série je cherche le caractère '>', ainsi je suis certain que le NodeMCU a bien redémarré.
+
+* J'ai aussi diminué le délai d'attente entre chaque ligne, passé de 0.3 sec à 0.03 sec. Les téléchargements sont donc 10x plus rapides
+
+* J'ai aussi mis un nouveau telnet serveur qui tient compte des tailles maximales des paquets TCP
+
+* J'ai aussi bien amélioré le script luatool.py (voir le code source)
+
+
+## Installation
+Maintenant c'est très facile de télécharger tout un projet sur un NodeMCU. Il suffit simplement de modifier le petit script bash upload.sh, puis de faire:
+
+```
+./upload.sh
+```
+* A chaque utilisation de luatool.py, le NodeMCU, s'il est branché sur le port série, redémarre !
+* S'il y a des erreurs lors d'un téléchargement, il faut simplement augmenter un peu le délai !<br>
+* Il est préférable de télécharger en premier les *gros* fichiers .lua !
+
+
+## Test via WIFI en telnet
+Après avoir installé tout le *binz* sur le NodeMCU avec le script *upload.sh*, on peut utiliser *luatool.py* via le WIFI.<br>
+On peut le tester avec le petit script:
+```
+./test_toto-sh
+```
+
+* Si cela fonctionne, la LED devrait arrêter de clignoter ;-)
+
+
+## Goodies
+### Quelques commandes en WIFI ;-)
+**ATTENTION:** ces exemples de commandes sont pour MON adresse IP actuelle de mon NodeMCU ;-)
+
+Help du luatool.py
+```
+./luatool.py -h
+```
+
+Liste les fichiers qui se trouvent sur le NodeMCU
+```
+./luatool.py --ip 192.168.0.157 -l
+```
+
+Télécharge le fichier *toto.lua* sur le NodeMCU
+```
+./luatool.py --ip 192.168.0.157 -f toto.lua
+```
+
+Télécharge le fichier *toto.lua* sur le NodeMCU, mais le renomme en *tutu.lua* et affiche une *progression bar* de l'évolution du téléchargement
+```
+./luatool.py --ip 192.168.0.157 -f toto.lua -t tutu.lua
