3G/GPRS module data not available

Post by dyn002000 » Wed Jan 23, 2019 9:22 am

Hi Libelium Tech,
I'm using a SIM5218E 3G/GPRS module, with the example 3G_28 - Start GPS and get GPS info. I'm sure that I have all the antenna well connected, and the battery charged, but I just can't get any information: it shows all the time data not available.

Here is what it looks like when using the debug mode 1:

Code: Select all

Hi,

Did you test the device outside? The node must have direct line of sight to the sky in order to achieve a good coverage.

Regards
