Finally got a chance to work with the nRF9160-Feather:
D:\Downloads\nRF9160-Feather>newtmgr -c serial image upload serial_lte_modem.bin
173.52 KiB / 173.52 KiB [=======================================================================================] 100.00% 15.54 KiB/s 11s
I used the serial_lte_modem_bb259bf.zip and renamed it serial_lte_modem.bin and loaded it with newtmgr but nothing, green led on constant, yes I re-powered the device. This upload was after the:
newtmgr -c serial image upload at-client-v1.3.2.bin
and it did the same, nothing.
After waiting on Verizon to get back to me I tried a Hologram SIM, I have many, but the feather was running something and it was hard to get a AT command in. I wanted to try another vendors SIM that does work with Verizon but first I need an AT interface. Seemed simple enough, DFU load bin…. both bin files are under 150K
