Hi @rmarlan - Thanks for following up and sorry to hear this is preventing you to deploy the Nova R404 Engineering Samples.
Our conversations with u-blox and further testing continue to show that the R404 is not ready for prime time production scenarios which is why we intentionally released these as engineering samples. We’re really excited about what Cat-M1 means as new IoT-focused radio access technology for cellular connectivity, but it’s a new technology with its own quirks as hardware providers, carriers, and IoT providers work to fully support it.
Because of these inconsistencies, we’re already working on the next run of a Cat-M Nova which will have support for both Cat-M1 and NB-IoT channels. Our goal is for the experience to be as reliable as our current 3G Nova and hope that the new module will peform better than R404s on existing samples. Our success team will also be reaching out directly with some follow-ups.
