FMC650 DNS failed to resolve domain.tld

Hello, i’m experiencing some issues with my first FMC650. Trying to set up GRPS connection, it isn’t able to resolve provided server domain name. It is, sometimes, able to send data to the server when is configured through static IP but most of the times nothing comes server side.
I’ve tried both 03.00.14.rev.11 and 03.00.15.Rev.09 firmwares with respective configurator application but nothing changes.

  1. Will “manual” network settings (like DNS server) be available into the configurator in further releases?
  2. Is needed to reboot device on each configuration change?
  3. A serial monitor page directly into the configurator application would be really comfortable instead of constantly dump logs into files in order to debug obscure behaviors…
    Below there is a log frame related to connecting in both mode:

within the same config it looks like it’s able to resolve DNS but throws anyway an error (pay also attention in AT+CIPSTATUS reply where protocol is correctly set as per configuration, with UDP):

Below, also, the section where it tries to send data to the server but nothing occours (neither the server receives data nor the FMC receives reply)

Hello Maynard,
I got a REV10 (still publicly unreleased) firmware version through my seller and managed to get it working.
