DRX activation with 1.28s period

[GiulianoFranchetto]

Hi,

We would like to activate the "legacy" 4G DRX with a period of 1.28s. Do you confirm that the needed AT command is: AT+CEDRXS=1,4,"0000" ?

If not, could you provide me with the correct AT command?

Hi!

By "legacy" 4G DRX, I am going to assume you mean DRX. Please correct me if I'm wrong. 

The AT-command you mentioned enables extended DRX, where the minimum interval you can set is 5.12 seconds. The DRX interval is determined by the network, and cannot be configured by the user, unfortunately.

Best regards,

Heidi

Hi,

I meant DRX indeed. 

Does it mean that the DRX is already activated by default?

Moreover:

From the datasheet + ETSI specification, this is not true. Why do you mention the 5.12 seconds limitation?

Most networks support DRX, yes.

If you take a look at the LTE-M Deployment Guide from GSMA

"It is recommended that LTE-M deployments support eDRX and to consider accepting the 3GPP Rel13 defined UE requested values of a minimum of 5.12 seconds, and maximum: 43.69 minutes."

Hi Heidi,

When I mean if the DRX is activated by default, I mean on the nrf9160. Do I need to use an AT command to enable DRx on the nRF9160, or is it enable by default once I AT+CFUN=1 ?

DRX is activated by default, you don't have to use an AT command.
