[SOLVED] I can´t communicate Goblin 2 with Ubidots example code

Hi.

I´ve been trying to test the Ubidots example code for the Goblin 2 board, I put in my token, ID variable and APN, but serial monitor only show hieroglyphics at 9600 Bauds, and if I change it to 115200 Bauds show me this.

START

+STIN: 25

+STIN: 25

+CPIN: READY

+STIN: 25

SMS DONE

+VOICEMAIL: INIT_STATE, 0, 0

PB DONE

This is my code.

Can you please say me what is wrong with the code?

Thanks in advances.

Greetings, can you be more specific about your issue? Is your device getting IP address from your IPS server? Have you tried to make a GET request to another site like google.com to discard hardware or connection issues?

You can find at our examples the proper way to build a TCP or HTTP payload, feel free to edit them to fit your needs.

All the best

Hi @jotathebest thanks for your reply.

It seems to be a problem with TiGO’s Colombia APN cuz my mate’s Goblin 2 works now perfect with another operator sim card. I will try to connect mine with his sim card just to dismiss a board malfunction.
