EC200A Reduce Power Consuption in Sleep

IoT Modules LTE Standard Module

Hi everyone,
I’m developing an application using the Quectel EC200A-EU module to enable communication between my custom board and a remote server. My goal is to send data to the server once every hour, and let the module stay in a low-power mode in the meantime.

However, I’ve noticed that even in sleep mode, the power consumption spikes approximately every second. I suspect this is due to the module checking the network (paging) to remain reachable.

I cannot disconnect it entirely from the network, as I need the module to remain remotely accessible for incoming commands or wake-up events.

So I’m looking for the best way to reduce power consumption while keeping the module registered and reachable. I’ve read about eDRX and PSM modes but I’m not sure how to configure them properly on the EC200A-EU, or which one would be more suitable for my use case.

Has anyone here successfully implemented low-power strategies with this module while maintaining network availability? Any tips or best practices would be greatly appreciated!

Hi，
I think both PSM and EDRX are more suitable for you.
Because both modes can request a fixed sleep time. Automatically wake up and connect to the network when you need it.
But these two modes can only perform data exchange after automatic wake-up or active wake-up. Unable to receive network information during its sleep period.
