Production Test Image for nRF91

[jing]

Where can i download the Production Test Image (PTI) mentioned in the nrf91_at_commands document?

thank you

it seems that the PTI is necessary for complete production test. but it is only pre-programmed in brand new device and not able to get it by other ways. so if a normal modem FW is programmed, the device can no longer perform production test.

is that so?

This is correct. The nRF9160 is preprogrammed with PTI (prod. test image), and there are certain AT commands that are restricted to this PTI firmware.

 

Kind regards,
