New firmware release v1.16.0.b1 (LoRaWAN 1.0.2 multi-region support)

[Tombee]

@rskoniec I used C:\Program Files\Pycom\Pycom Firmware Update\pycom-fwtool-cli.exe --verbose -p com13 lpwan --region "US915"
but after a Connecting ........................................____ shows for about 15 seconds it ends with
Exception: Failed to connect to ESP32: Timed out waiting for packet header, on line 351
Suggestions?

@tombee Press the reset button, Make sure all other programs that use the COM port are not connect, verify the the device is actually going into programming mode by opening a COM port and seeing the waiting for download message.

@ssmith I pushed the reset button prior to each attempt and the LoPy flashed green.
I was able to install using the GUI version but seem stuck at getting the US915 region setup when using the command line version. I am using a Windows 7 64bit computer where I was able to find the Pycom Firmware Update directory. It doesn;t show up in my Windows 10 pc directories.

@tombee From the output it looks like you are using an Expansion Board 2.0

Did you install the jumper wire the same way you do when using the GUI firmware update tool?

[Xykon]

@marcobenini I have uploaded a new version that should fix this. Please try downloading https://software.pycom.io/downloads/pycom_firmware_update_1.10.1.b3.tar.gz again.

I have made another small correction after uploading this release without increasing the version again, so if you've downloaded the new version earlier please try downloading it again.

If you still have issues with this version please let me know.

@tombee Here's the command I used with no issues on a Win10 machine..
pycom-fwtool-cli -p com7 flash -t LoPy4-1.16.0.b1_Steve_mod.tar.gz
Sounds like the program is not even seeing the device from your error message. Verify that it is actually going into download mode. I didn't set the region in the download command.

@xykon It is the same USB connector (com13) on the same Win7 pc. I can run the GUi update and it completes successfully. I can then connect with TeraTerm and run REPL
But it won't run the CLI version

I am using the pysense board. Don't have the expansion board to try. So I didn't use any jumper wire when using the GUI

[Xykon]

@tombee Do you have any anti-virus or security software installed?

[Tombee]

@xykon Windows Defender on Win10, AVG on WIn7.
I disabled AVG and tried again with different error
Invalid head of packet <'\xe4'>, on line 351.
PS: Since I don't have a reputation yet I must wait 600 seconds between posts :-(

[Xykon]

@tombee I think I know what the problem is. Are you OK to wait until tomorrow as you said the GUI version is working?

[Tombee]

@xykon I will wait as necessary but am frustrated in my attempt to get this operational in US915 bands as I live in Canada and cannot legitimately use 868.1

[MarcoBenini]

@xykon I tried the newer upgrade version, it fails also this one, but happens some steps after.
Now it lets select the LoRa region (868 MHz for me), than shows messages for searching / downloading firmware and than stops after

"...
Please be patient while the firmware is │
│ being uploaded to the board. │
│ │
│ (this can take up to a minute). │
.."
..." Exception: Failed to connect to ESP32: Timed out waiting for packet header, on line 351 ..."

I find also difficult to know when is the right moment to push the reset button, I arrive to arrive to go on 1 - 2 times every 10 .
Maybe an intermediate screen, after port and speed check could be useful, asking to push reset button could be useful.

With the other m procedure, using bin/upgrade.py, is easier to do, but maybe a little bit intimidating for new users.

note: I did all the tries with "sudo" so no write permissions problems.

The command line updater failed (Debian) with this error: "Something failed trying to connect to the device." After this step: "Connecting to the device to get it's information, please wait."

Also saw this error message:
"Exception: Failed to connect to ESP32: Timed out waiting for packet header, on line 351"

With the gui version everything worked fine. I had to install python-qt4 to get the gui version working.

Edit: same issue as below
