How to enable PSM/queued mode on Thingy/DK

[always]

We have been testing the DK board and Thingy:91 and had a few questions on enabling PSM/queued mode.

We are able to enable queued mode for the lwm2m_client example on the DK board but haven’t been able to for the asset_tracker example on either the DK or Thingy:91.

We have been working on this from Linux, Windows and Mac. The DK version is 2019.20 and Thingy91 is 2020:18.

Here are the settings that have been changed in prj.conf from the defaults and my monitor output below.

CONFIG_POWER_OPTIMIZATION_ENABLE=y

CONFIG_LTE_PSM_REQ_RPTAU="10101010"

CONFIG_LTE_PSM_REQ_RAT="00100001"

Hi!

I'm sorry for the late reply, we're a bit short-staffed during the summer months.

Not sure what Queded Mode in LwM2M has to do with PSM. But you can use the LTE link controller library, specifically the lte_lc_psm_req() function to enable PSM in your application. 

Have you seen this documentation about Queue Mode support in the LwM2M client sample?

Best regards,

Heidi
