I have a SODAQ SARA AFF R410M “Connected by Vodafone” and I am now in the Netherlands.
I try to use the Board with a T-Mobile NL SIM Card. The first AT command gets prompted with OK. Then the boards hangs up.
When I do the same procedure with a Vodafone SIM Card or without SIM Card, I can continue to prompt AT Commands.
Why can I not use a T-Mobile SIM? Why does the board die? Is there a SIM Lock?
Can you post the sketch you were using to test this?
We will try an replicate the issue here (using a T-Mobile NL sim).
I Programmed a PassThrough
when I send the “AT” directly after programming. Then it stops responding at all.
I am 30 minutes from you, so I can bring the board with me and the TM NL simcard.
/* SODAQ SARA */
#define DEBUG_STREAM SerialUSB
#define MODEM_STREAM Serial1
#error "Please select the SODAQ SARA as your board"
unsigned long baud = 115200;
// Start communication
// Forward every message to the other serial
Hi, Gabriel, were you able to replicate this problem? Did you solve it? Sincerly, Andreas
Sorry for the delay, we should be able to give you a response soon.
What Serial Monitor/Terminal are you using?
If you use the Arduino IDE can you update to the latest version 1.8.7?
