Hi
I finaly got my MKR 1400 and started testing it with the basic examples. TestMode, TestGPRS, GPRSPing.
The first problem I got was the power issue. I forgot to power it with more juice.
Its now powered from 4 li-ion 18650 batteris in parallel. The voltage is 3.98 and dont drop. I connected a capacitor to make everything even more stable, just in case.
First I tried connecting my data SIM and nothing worked except the TestModem sketch. But that sketch dont need a SIM card. When I connect my "normal" phone SIM card for calling and data usage, everything works great and I get a ping from google with the GPRSPing sketch. It looks like there is an issue with the data SIM I have.
I though first the data SIM was not working. So I testes the SIM card in my phone and got no issues there. I could surf the web and download files. I did remove the stock PIN and changed it to 0000. But it did not help. The reason I was testing with my datasim was because I have one for free in my tele subscription.
So my question is. Does the Arduino MKR 1400 only support SIM card you can call with?
Would appreciate to get some answers, thanks.
My setup is
MKR 1400
Battery power (Should be around 4-6A in total)
SIM card from Telia in Norway
GprsPing code from the example
/*
