Hello World example somehow blocked

[Unitech]

I've followed the quick start guide and once my ESP32 TTGO board has been flashed, it sends only one message and then stops.

On the ttn console looks like the message is in "retry":

And on the console it never prints "Message sent":

I (328) cpu_start: Starting scheduler on PRO CPU.
I (0) cpu_start: Starting scheduler on APP CPU.
I (421) ttn_hal: IO initialized
I (421) ttn_hal: SPI initialized
I (421) ttn_hal: Timer initialized
I (451) ttn_prov: Dev and app EUI and app key saved in NVS storage
I (461) ttn_prov: Dev and app EUI and app key saved in NVS storage

I (11871) ttn: event EV_JOINED
Joined.
Sending message...
I (11871) ttn: event EV_TXSTART
I (12911) ttn: event EV_RXSTART

(no "Message Sent" print here for more than 2 minutes).

Would you know what is related to?

Thank you

Looks like it's something related with the TTGO board, I tried on another ESP32/Lora from Heltec and it worked as expected

Changing the board and pins configuration as noted on the wiki made the trick

Thank you a bunch @manuelbl for this quality library
