I'm trying desperately to send a notification from my Arduino Mega 2560 to my iPhone thanks to Pushsafer.

I have used the example sendEvent available on Github, but it doesn't seem to work. I have obviously replace the network SSID, network key and the PushsaferKey. It seems to work, but I don't receive the notification

Here is the message that I have when I drop the sketch to the WeMos :
Executable segment sizes:
IROM : 246632 - code in flash (default or ICACHE_FLASH_ATTR)
IRAM : 26892 / 32768 - code in IRAM (ICACHE_RAM_ATTR, ISRs...)
DATA : 1272 ) - initialized variables (global, static) in RAM/HEAP
RODATA : 1192 ) / 81920 - constants (global, static) in RAM/HEAP
BSS : 29168 ) - zeroed variables (global, static) in RAM/HEAP
Le croquis utilise 275988 octets (26%) de l'espace de stockage de programmes. Le maximum est de 1044464 octets.
Les variables globales utilisent 31632 octets (38%) de mémoire dynamique, ce qui laisse 50288 octets pour les variables locales. Le maximum est de 81920 octets.
