New firmware release, version 1.6.0.b1

[Neo]

@livius Thanks. This solution is definitely not for real deployed systems. I mean we are forced to deploy a light sensor in order to read the temperature. Waste of energy and money.

What I2C light sensor are you using for this workarround? We would like to investigate it.

[livius]

@Neo
yes, definitely not for real deployed systems but if I2C is still software than maybe still required
i use BH1750.

[Neo]

@livius Yes. One LoPy and one DS1b20... and empty output. As far as I remember this was happen also on Wipy 1.5.1b1 but I will check again

@Pete said in New firmware release, version 1.6.0.b1:
Which different brand of WiFi IoT module are you using?

[Pete]

@Colateral I ordered some of these: LinkIt Smart 7688 at the same time as my WiPys. Similar form factor, but runs OpenWrt, a Linux distro originally developed for customising Linksys routers. They arrived at the start of this week. I haven't even opened the box yet, as I'd like to get the WiPy working if I can - my use case is pretty simple and I'd rather not have to admin a whole Linux if I can just write one Python script instead. From the point of view of attack surface if nothing else. But it's a second basket for my eggs if required.

@daniel

i still have problem of corruption of files stored throught ftp :(

[daniel]

Hello,

We just released new firmware, version 1.6.2.b1. These are the changes:

• Fix issue when trying to send empty strings via sockets.
• Update the ESP-IDF.
• Correct RCZ3 uplink frequency and integers overflow.
• Implement ntp_sync for RTC. Add simple support for timezones. See: https://docs.pycom.io/pycom_esp32/library/machine.RTC.html#machine.rtc.ntp_sync
• Correctly set the DNS server. Also disable and enable the right TCP adapter interface.

Cheers,
Daniel

@livius Really? We have been testing a lot during the last 2 weeks with large files and the issue seem resolved. Does it happen when you perform file operations in your script while at the same time the FTP server is busy with a transfer?

[livius]

@daniel
it is by copy file throught e.g. filezilla and without while true: loop

[daniel]

@livius what's the size of the file?

[daniel]

@livius could it be that your file system is corrupted from previous firmware versions? Could you try:

import os
os.mkfs('/flash')

to format the file system and start from scratch...

Cheers,
Daniel

I will test with 1.6.2 and will see if something changed

could it be that your file system is corrupted from previous firmware versions? Could you try:

I can erase all data - but i can back tomorrow with review

@daniel With 1.6.1, I encountered some instabilities : the lopy hangs when trying to sync the project from Pymakr, and when I call gc.collect(). Are you aware of these issues? Is it possible that they are fixed in 1.6.2?

Thanks

[daniel]

@livius can you show me an example of the gc.collect() crash?

[JF002]

@daniel

import gc
gc.collect()

Just freeze my lopy. I noticed it when trying to fix another issue with ds1820 and mqtt : https://forum.pycom.io/topic/670/onewire-wifi-mqtt-crash/7

Just freeze my lopy. I noticed it when trying to fix another issue with ds1820 and mqtt :

OK it happens, not always at the first time. I'm working on it... Wait for the 1.6.3.b1 coming a bit later...

Yeah, thank you! You're the best!

[daniel]

Hello,

1.6.3.b1 is out there. In my tests the gc.collect() problem is now fixed. @livius @JF002 please test and let me know... Thanks!

Cheers,
Daniel

[Neo]

@daniel Still hanging on LopY. In our script this is happening after wifi STA connect ... we have a gc.mem_free call. We removed all gc collect calls.

[daniel]

Then it's not the gc anymore in your case. If you can share with me a piece of code that can reproduce it I'll get onto it.

Cheers,
Daniel
