Hi, Is there a way to configure/reduce the time taken for the RC7620 module to send the RRC release indicaiton to the network after data is sent so it can enter RRC Idle state and sleep? Currently it takes about 5 seconds, but we’ve worked with other modules that can enter a sleep state in about 1…

Have you tried to set to usb selective suspend mode from the host? [image] USB-SS mode RC76 How to put the RC7620 modem in USB_SS mode? Does modem go to USB_SS automatically when nothing is keeping it awake? Or we need to configure it first to do that? I have R9 firmware …

Yep, I’ve been able to get the modem to sleep on USB SS. It will sleep immediately if it’s in RRC IDLE (from !GSTATUS), but if !GSTATUS shows RRC CONNECTED there’s a 5s window where the current is 60mA, until it goes into RRC IDLE, at which point the linux host suspends the USB device and current d…

is this related to the eDRX mode controlled by AT+CEDRXS?

I don’t think so, I’ve tried different CEDRXS parameters but it doesn’t affect the power consumption in the window we’re interested in. We want to reduce current during the 5s window after network activity stops (I think this is C-DRX mode) but before the module goes to sleep (I think I-DRX/paging m…
