New Firmware Release 1.20.2.rc6

dgerman

@rcolistete from my notes (as I cannot access system) Is this what you are looking for?

os.uname():
1/07/20 (sysname='GPy', nodename='GPy', release='1.18.1.r2', version='v1.8.6-849-f652205 on 2018-10-18', machine='GPy with ESP32')

I did NOT know I was supposed to erase flash first.
Thanks for including the command.

I extracted pycom-fwtool-cli from the Pycom Firmware Update.app and ran

pycom-fwtool-cli list 
pycom-fwtool-cli -p /dev/cu.usbmodemPy0d3d0c1 erase_all 
 Running in PIC mode
 Erasing the board can take up to 40 seconds.
  Board erased successfully in 12.51 seconds

Then ran Pycom Firmware Update.app which ran as previously.

The GPy now blinks heartbeat and broadcasts SSID gpy-wlan-7b7c as expected at least a few times. But the Mac book pro that previously connected to it as an access point does not offer to connect to it. After 60 seconds it no longer appears in the list of networks shown by apple's airport utility (I expect that the first(few?) broadcast, retained in cache expired)

Just to be redundant(?) I did the erase_all again and ran the update again but still no joy.

I await addition assistance, Thank you

@dgerman said in New Firmware Release 1.20.2.rc6:

wlan = WLAN(mode=WLAN.STA)

For my understanding, do you want to put the GPy into STA mode or in AP mode? If you want AP mode, can you then try without your boot.py and main.py?

dgerman

@peterp Thank you for your response.
After erase_all and flash I expect GPy to be blinking heartbeat and to be in Acces Point mode broadcasting SSID of gpy-wlan-xxxx (where xxxx are low order digits from MAC) with a password of www.pycom.io with a telnet server and ftp server running at 192.168.4.1 .
This is what I expect now but it seems to broadcast SSID only once (or a few times) ( I am using Mac Boot Pro , Catalina 10.15.4 which prior to flash 1.20.2.rc6 offered to connect and the airport utility continuously reported it's RSSI.)

peterp

@dgerman Understood. And are you able to test that AP behaviour after temporarily removing your boot.py and main.py?

dgerman

@peterp After erase_all and flash my boot.py and main.py are no longer there as I can tell by the heartbeat.
I cannot connect to Access Point to put them there.

I notice the only difference between multiple reports is

Extra: Last beacon: 30ms ago
Extra: Last beacon: 2070ms ago
Extra: Last beacon: 4260ms ago

Which seems to confirm my suspicion that GPy is only broadcasting SSID once.
I don't know how to interpret anything else in the report.

If I download and flash a previous version of the firmware for GPy where should I get it? I am using a Mac so how do I get Pycom Firmware Update.app to flash a specific version?

@dgerman said in New Firmware Release 1.20.2.rc6:

@peterp After erase_all and flash my boot.py and main.py are no longer there

Ugh, yeah, of course. Sorry, wasn't thinking along properly here. Mhm ... it's weird ... I'm thinking ...

I cannot connect to Access Point to put them there.

just for completeness, you know you can work with pymakr?

If I download and flash a previous version of the firmware for GPy where should I get it? I am using a Mac so how do I get Pycom Firmware Update.app to flash a specific version?

you should be able to select previous version also in the application ... if you want to download them manually, see here https://software.pycom.io/downloads/GPy.html

dgerman

@peterp Thanks. On Mac OS with Pycom Firmware Update.app include develop versions I choose
GPy-1.20.2.rc2 ++SUCCESS++
GPy-1.20.2.rc3 --FAILS only transmits SSID once---
GPy-1.20.2.rc2 --FAILS !-!
GPy-1.20.2.rc2 with erase file system ++SUCCESS++

Did not see rc4 or rc5.

dgerman

@peterp Should I create an issue at GitHub?

robert-hh

@dgerman Can you show the full log you see in a console window after pushing reset?

dgerman

@robert-hh Sorry I don't understand what you are asking for.
Summary:
GPy 1.18.1.r2 (as received)
boot.py set LED green, pink, connects to wlan as STAtion and finally green.
main.py updates time from ntp sets LED blue then sends syslog message.
After update to 1.20.2.rc6 LED blinks but no syslog message is received. GPy does not respond to ping, telnet or ftp.
After erase_all and update, LED shows heartbeat (since boot.py and main.py were initialized as empty). GPy transmits SSID as AccessPoint one time only and macBookPro can no longer connect.

robert-hh

@dgerman If you connect your GPy to a terminal emulator and push the reset button, then you'll get some messages. These are the ones I'm asking for. Sample witth a LoPy4 below:

@robert-hh I only ever connect to GPy in the traditional headless manner (I initially only had a GPy board , no expansion board, no USB). I created a boot.py to set it up as a STAtion, established a wifi connection on MacBook Pro to the SSID gpy-wlan-7b7c and ftp'ed boot.py. After reset I use ftp to update boot.py and main.py. I telnet to it test code snippets in REPL.

If you provide me code to retrieve the values you are interested in I can use REPL to display them or I can put them in a main.py and write the values to a file and retrieve it with ftp.
