Thank you for the update, this sounds promising.

You may use the command at the beginning of your application by using at_cmd_write(). An alternative is to add 'CONFIG_PDN_LEGACY_PCO=y' to your prj.conf file.

For reference: CONFIG_PDN_LEGACY_PCO

It works, and as I can save it by sending the AT+CFUN=0 command after the setting, I have overcome my development needs so far.

But for production I need a way to send it from firmware... The SDK 1.7.1 seems to not handle at all this command at configuration level..

Possibly it is in order to allow for flexibility to do it in run time, but then where is the most suitable place in code to add it programmatically?

What happens if you fire the following?

AT%XEPCO=0

In SDK v1.4.0 there is configuration option <LTE_LEGACY_PCO_MODE> in the LTE link control library Kconfig.

I've set it from there with the SEGGER Embedded Studio Configurator tool by checking the "Enable legacy LTE Protocol Configuration Options" checkbox...

This is what I am looking for and I can't find in SDK v1.7.1

How did you set the Legacy PCO mode?

Did you try the following(XEPCO)?

AT%XEPCO=0

Hi,

Both prebuilt

nrf9160dk_asset_tracker_v2_debug_nbiot_legacy_pco_2021-10-20_d29f1dde.hex

and

nrf9160dk_asset_tracker_debug_nbiot_legacy_pco_2021-10-20_d29f1dde.hex

fail in different ways.

I have managed to build and run the asset tracker sample with SDK 1.4.0 but I cant find the PCO mode configuration in SDK 1.7.1

In the sample projects in Segger Embedded Studio though there is no differentiation on asset_tracker V1 and V2.. That is while in the prebuild hex files I can see a different V2 file, I don't know how to select the V2 sample source...

Hi Vassillis,

Are you using the now deprecated nRF9160: Asset Tracker? Have you tried nRF9160: Asset Tracker v2?

Best regards,

Håkon
