Description

Hi,

I am having quite trouble by using UBLOX SARA-G350. Basically, it does not work at all. I have taken the HTTP client example sketch, but I am viewing the following issues:

  1. The initialization prints sometimes the correct model (### Modem: u-blox SARA-G350), most often the generic string in case of error (### Modem: u-blox Cellular Modem)
  2. When the sketch tries to perform gprsConnect() almost always fails.
  3. In the rare cases when gprsConnect() succeed, the HTTP request fails.

According with the chip manual, the modem reset should be hold down for at least 5ms, during initialization. Actually, I have tested various delays, but non of them works...

Does anyone have my same issues? Can someone please confirm that UBLOX SARA-G350 works fine?

Thanks, regards.

Were you ever able to resolve this? I know some other firmwares of u-blox modems have been nearly-non-functional. See #296

Hi,

thank you for letting me know about the other similar issue. No, I was not able to let it work, and now I am working with another modem. Maybe (hopefully) in January I will be able to test it again (right now I am full on other stuff).

Regards.
