Hi,

Please see our Application Note on production programming of the nRF9160 for more details, but to answer your questions directly:

[quote user=""]Can we combine the modem firmware and the application sw into one image[/quote]

No, this is not possible.

You are technically doing DFU of the modem, and you therefore need an application running on the application core that can transfer the modem image to the modem.

For more details about this, see the app note linked above.

[quote user=""]Are there any fast programmer tools (hw/sw) we can use? [/quote]

Any compatible production programmer can be used.

Also, be aware that due to Christmas vacations, response times might be slower than normal.

Best regards,

Didrik
