New Firmware Release 1.20.2.rc9

[peterp]

A new firmware release 1.20.2.rc9 is now available.

Some of you noticed that we recently also sneaked out an rc7 without a forum announcement. Apologies for that. The changes below summarize both releases.

Changes:

• LTE: add PSM Power Saving Mode
• Pybytes 1.5.0
• bugfixes

The firmware packages (.tar.gz) can be downloaded from the docs.

The elf files for both release candidates can now also be found on github as usual.

Great! the LTE-PSM is exactly what I was waiting for. But are there any instructions / samples on how to use it ?

Yes, you can see the example here https://development.pycom.io/tutorials/lte/power/#power-saving-mode and there are some explanations in the API docs as well for lte.init() and lte.psm(). Hth!

Hi @peterp

As usual, I think it would be wise to specify in the documentation (both in the tutorial and in the reference) what minimum firmware release is required for those examples / parameters / functions to work. It will avoid many headaches.

Also, it would probably be wise to make the "development version" more obvious (and possibly be clearer as to what versions are "development").

Finally, does this work for both Cat-M1 and NB-IoT or only one of them?

@jcaron To get 25uA PSM deepsleep on a FiPy I had to have the latest firmware in both the modem (LR5.2.1.0-48829) & the FiPy(1.20.2.rc9).
