LoPy deep sleep mode ?

[daniel]

@jasonriedy thanks and good points. We are carrying out deep sleep tests both firmware and hardware related to find the issues. I expect to have answers next week. In the meantime, we have received the pre-production OEM modules of LoPy and WiPy (L10 and W01) and we will be publishing some details later today both on the deep sleep mode and the new 4MByte RAM. All very promising.

Cheers,
Daniel

@daniel
4MByte RAM - finally! :)
Is this only for OEM or normal modules too?
For prototyping i use normal modules - after success i will go into OEM

@daniel Remember we are having these same issues but we are running SiPy. I know they have same footprint, but be sure to test and push firmware update for SiPy also :)

I like the idea of 4MB RAM but those SPI pSRAM chips don't run off magic :) it will mean increased power usage - though maybe offset if it reduces Flash memory access.

@jmarcelino
Will be good to see some details/comparision with current

@livius
as we can see in
https://forum.pycom.io/topic/989/pycom-oem-modules-are-here-4-mbytes-of-ram-and-deep-sleep-test
we should not worry :)

@daniel
Have you made any progress on the deep sleep mode issue yet ?
As many on this thread I rely a lot on this feature for our project to work out (small battery, long life, infrequent LoRa communication....)

@gael-wogenstahl @daniel Heard! I also think we are a lot of devs missing maybe the most fundamental feature of a board branded as ideal for IoT applications. Remember we are having the issue on Sipy!
