Just found out about this example. I believe it uses both LTE and GPS concurrently.

Hi Hakon,

Just wondering if you had an update on this. Also if you could contribute on whether it's possible to have edrx and GPS running concurrently.

[quote user=""]I would also like to change the edrx period, if possible. What is the default? What is the procedure to change it?[/quote]

You can set the CONFIG_LTE_EDRX_REQ_VALUE option in prj.conf, or use the +CEDRXS command to set the edrx cycle duration. CONFIG_LTE_EDRX_REQ_VALUE is set to "1000" by default.

[quote user=""]What is the procedure to prepare the project for using edrx/spm (settings in prj.conf, etc)?[/quote]

You need to set CONFIG_LTE_EDRX_REQ=y in prj.conf.

I'm not sure if it's possible without the use of modem trace. I will report back if I find a way to do it.
