LoRa32u4 EV_JOINING

Hi,

I have a gateway LG01 and for the device i use this wiki to upload a sketch to the LoRa32u4 (v 1.2) : https://wikifab.org/wiki/Créer_une_application_avec_Lora32u4_pour_The_Things_Network

I receive an activation message on TTN console and the device said this on serial :
Starting
Packet queued
3343461: EV_JOINING

But i wait for EV_JOINED (and transmission)…

What’s going wrong ?

Thank in advance.
