Same here; POST just looks Ok, but i can´t get any response using GET
Any ideas?

Hi there:
Just a lucky guess but...maybe the mp3's bitrate or frequency is too high to be played?
Try with a 128 Kpbs, maybe it'll work.
Keep us posted.

Mine worked out of the box; ¿Have you tried with another SIM? Is the signal strong enough in your room? ¿Does the speaker play any sound when trying to call?

Best regards,
David.

Hi there:
Remember to disable the SIM's PIN, or you'll be unable to use it.
Keep us posted!

I'm also willing some POST / GET examples, (basically bought the kit for that purpose)

Hi there:
Yes, after uploading the Arduino firmware, you lose the default UI; it works only as a Arduino should. Anyway, if you upload the LDisplay example, you can turn on the display again and try some graphic functions.

Cheers, that was a nice advance!
i'm also looking for a proper way to handle POST and GET JSONs through https; Hope some kind of example comes soon.
Ty vm for your effort!

Dear all:
I'm trying to manage two devices with UART from the rephone; I've seen some rephone arduino examples using Serial1; (LMOTOR i.e.) so my question is, can we use two sets of Rx / Tx ports; if so, what pins from the breakout can we use for the additional ports?

The only way without battery, is throught the VCC & GND pins.
I've tried with only USB / no batt and got same result.
