Hi,
Can someone pelase confirm if EC800G has sleep mode? is it same as eDRX mode?
Also, more importantly, does any provider in India support the edrx mode?
Thanks,
Sandeep
Yes, the Quectel EC800G module features sleep mode. However, this differs from 3GPP-based advanced power-saving mechanisms such as eDRX (Extended Discontinuous Reception) and PSM (Power Saving Mode).
Sleep/Deep Sleep also reduces power consumption by shutting down the module’s internal processor. It can be enabled on the AT side with AT+QSCLK=1.
The ql_autosleep_enable(QL_ALLOW_SLEEP) API can be used in SDK-based applications.
PSM (Power Saving Mode) is also enabled with the AT+CPSMS command. In this mode, the module remains connected to the grid but disconnects the carrier. It wakes up again when an uplink is available or the T3412 timer expires.
eDRX (Extended DRX) is enabled with the AT+CEDRXS command. It operates in idle mode, allowing the module to listen for paging only at specific intervals (e.g., 20.48s, 81.92s). This reduces power consumption but increases downlink latency.
Key Difference
Sleep mode = low-power state at the module’s hardware level
eDRX/PSM = network-coordinated, protocol-level low-power modes
These modes can be used together to complement each other.
In India, eDRX and PSM commands can be sent at any time on the EC800G module, but their activation depends on operator support.
From my research, Reliance Jio and Vodafone Idea (Vi) offer eDRX/PSM support with their LTE-M/NB-IoT services.
Limited support has been reported in some regions of Airtel.
In summary: The EC800G supports both sleep mode (QSCLK) and advanced power-saving modes such as eDRX/PSM. Sleep mode and eDRX are not the same; However, when used together, the device’s battery life can be significantly extended.
Dear customer,
We apologize for the delayed response.
Could you please confirm if the issue has been resolved?
