[Hoang]

Dear, 

I am using ncs_v1.0.0_rc4, and got the FW mfw-nrf9160-1.0.0-25-rc2.prealpha from Bjørn Kvaale.  I want to update this FW

mfw-nrf9160-1.0.0-25-rc2.prealpha.zip

I tried to use nRF Connect v3.0.0 Programmer 

/Cellular modem/ Update modem. But it didn’t work

Modem DFU failed with error: Error: Error occured when program. Errorcode: CouldNotCallFunction (0x9) Lowlevel error: Unknown value (ffffff5e)

How can I do it? Can I use nrf9160_mdm_dfu –update ?

 

Thanks

Hello Hoang!

I can confirm that this fails on my DK aswell. Is it any reason you're not using the newest modem firmware available? It can be found at this location.

Dear Carl, 

I am testing ncs_v1.0.0_rc4 - I want to get the real position when I run asset_tracker. With ncs_v1.0.0, the positions are not my

Hello again!

The newest modem firmware have support for real GPS data, so you should definitely update, regardless of your NCS version.

Furthermore it's true that ncs_v1.0.0 doesn't support real GPS in the asset_tracker, but this is also true for ncs_v1.0.0_rc4. 

You should check out this pull request for NCS. It's the only example I can find where asset_tracker uses real GPS data.

All the best

Just for info: the modem prevents downgrading of it's firmware, so it will fail if you previously have upgraded to a newer release.
