@Stefan-de-Lange Thanks for the suggestion! We already have most of our development done with our own PCB using an ESP32 and SIM7020E. What I can gather about the nRF9160 is that we can either use a full DK or the SiP. Both seem prohibitive, as it would be wayyyy more work than just switching out the SIM breakout and changing AT commands and routines and such.
Am I correct in thinking this? I’d very much love to have (more) reliable data transfer, but also don’t have the time to do a large overhaul.
