Are there users who can make the Explorer board into sleep with a very low power consumption ?
I can get the Lora module to sleep correcty, I see the current decrease with about 3mA (== RN consumption ) ( sys sleep command after a reset, wait a while after the sys sleep command )
I disable the USB of the uP with USB->DEVICE.CTRLA.reg &= ~USB_CTRLA_ENABLE;
I set the uP to deep sleep mode with SCB->SCR |= SCB_SCR_SLEEPDEEP_Msk;
And I set the processor to sleep with __WFI();
Watchdog timer is set and active, though this doesn’t seem to draw a lot.
But the Bluetooth module of the Explorer, this bothers me a bit, I pull the reset line of Bluetooth low to let the module inactive. ( Have already tried it with SW command ‘Shutdown’, and making the Wakup pin High ( used the Sodaq Library of course )
Lowest amount of current stays around 800uA, as 50uA would be possible ??
I have a latest model Explorer, so also with the RN2483A version Lora module; the power consumption bug in this version should be solved if I’m correct ?
Is there another chip on the board I must command to sleep perhaps ?
PS I do measure current when powering the module through the on-board battery.
Does the MCP1711 regulator draw this much current perhaps ?? It shouldn’t be doing it I suppose.
So with this I’m curious if there are any other Explorer users who want to let their board deep sleep with a very low power consumption.
