Just trying to get po working on Gitpod.io
https://gitpod.io/#github.com/hpssjellis/gitpod-po-util
This works, latest snapshot
In the above snapshot, my Oct 2019 Particle Argon build has already generated the .bin file, however you can't flash from a browser so the file will need to be downloaded to your machine and then install particle-cli and flash from your machine
particle flash --usb myArgonProject-argon.bin
Old generic instructions
sudo apt install curl
bash <(curl -sL get.po-util.com)
po init argon myProjectName
cd myProjectName
## monolithic Build of Mesh Devices (full load of firmware to device)
po config mesh-develop
po setup-mesh
MODULAR=n po argon build
## normal building of Mesh Devices
## po config v0.8.0-rc.27
## po argon build
particle cloud login
## enter your particle userName then password
## see if your Argon is flashing cyan and online
particle list
## flash your code to the Argon over the air
po argon ota myArgonName
## actually nowI am preferring to use DFU mode since it acknowledges success
## on cloud9 I download the .bin and then use particle-cli to do the command
## on a local machine just run this
## dfu mode flashing yellow hold mode button tap reset about 5 seconds past flashing purple safe mode.
particle flash --usb myArgonName.firmware.bin
