NRF9151 modem init error -116

[Jason]

After full update modem firmware and reboot, i got this error:

E: Modem library init error: -116, lte_lc not initialized

The only way to work around is power cycle.Post

Hi

Are you seeing this issue on an nRF9151 DK or on a custom board? My first guess is that the modem library is still in DFU mode after the modem firmware update, and that you need shut it down with nrf_modem_shutdown() before initializing it in NORMAL MODE. I assume that's what happening in a power cycle that doesn't in a reboot on your end.

Best regards,

Simon
