Hi Eben,

Quick feedback: I can use GNSS and TCP at the same time using the SIM7000E using the latest firmware, which I had to update beforehand.

Best Regards,
Daniel

Hi Eben,

I should receive a SIM7000E tomorrow and I will test it. I hope the commands are identical or at least similar. Will revert back with my findings as soon as I get time to test.

Best Regards,

Hi Eben,

Here is the resource that I have found, it relates more to TCP, maybe UDP works.

https://stackoverflow.com/questions/61857667/sim7080g-module-cant-send-data-over-tcp-while-using-gnss

Thank you for testing this!

Hi Roland,

I also managed to send UDP packages so far.

I read a statement from SIMcom where it is mentioned that the module does not support LTE and GNSS functionality at the same time. Therefore, I am evaluating the SIM7000E soon. Not yet tested this myself.

Thank you,
Daniel

Hi,

A few days ago, I purchased two development boards. One of them is featuring the SIMcom7070G.

My location is Germany, I am using a SIM from the Netherlands with Roaming enabled.

I have not yet managed to send a message through but I can PING 172.27.131.100 - I hope that this module is compatible as it is not one of the recommended or approved one’s.

Here are the commands for a successful PING: (Some are probably redundant)
