Re: ble 2 sensors and 1 station?

Hi Lofer, Thanks for your attention, Bluetooth works fine with one pyb-d wich have a sensor, and one other pyb-d wich receive data from the first one pyb-d. I would like use 2, or more, pyb-d wich one with a sensor, and one pyb-d wich receive all data from others pyb-d. For moment when I tried to do...

Re: Driver for SCD30 CO2 Sensor

And I'm a newby with uasyncio...
I have just "create task"...
I think that with a "wait_for_event" it could be much more better... But I have to learn it...
If someone have an advise...

There, examples of what I have done with scd30:

Re: Driver for SCD30 CO2 Sensor

Yep,

I use the scd30:
- fewer crash with just a "time.sleep(2)" (this sensor need it).
- But, the best, for sure, is to use uasyncio library. Maybe just one crash per week with just one raspberry pico on 5.
- No one crash with alls pyboard-d.

Re: file corrupted and reset firmware no works

Yip, For moment it's all right with the pyb-d. It seems that with litlle_fs, it's going a litlle bit faster...? Otherwise, I tried to do the same with a pyboard. I can just format all flash mem. And then I have troubles with the use of sd card. So with a pyboard, the best is still original format fo...
