Typing vagrant from the command line will display a list of all available commands.

Be sure that you are in the same directory as the Vagrantfile when running these commands!

Creating a VM

• vagrant init -- Initialize Vagrant with a Vagrantfile and ./.vagrant directory, using no specified base image. Before you can do vagrant up, you'll need to specify a base image in the Vagrantfile.
• vagrant init <boxpath> -- Initialize Vagrant with a specific box. To find a box, go to the public Vagrant box catalog. When you find one you like, just replace it's name with boxpath. For example, vagrant init ubuntu/trusty64.

Starting a VM

• vagrant up -- starts vagrant environment (also provisions only on the FIRST vagrant up)

To get the channel id

1. Create your bot with botfather
2. Make you bot an admin of your channel

Simplest way (via @anhtuank7c)

Go to Telegram web and open a channel, get the ID from -[channel id] from hash in the path

Flashing CC2538 using OpenOCD (&UART)

Problem description

CC2538 SoCs are Cortex-M4 based SoCs by Texas Instruments for 802.15.4 PAN networking, especially for Zigbee communication using their Zigbee Stack solution. It also is a solid foundation for hobbyist-grade solutions involving Zigbee communication, especially for running a self-implemented Zigbee coordinator (often called "Zigbee gateway" in commercial distribution of similar tech). Software-wise, this is usually done by running "ZNP" (Zigbee Network Processor) firmware on the SoC and using a separate controller/computer to act as the "ZAP" (Zigbee Application Processor). In a hobbyist setting, the former is usually a cheap module from china containing the chip, capacitors and an antenna or antenna connector, while the latter is e.g. a Raspberry Pi or an Intel NUC or whatever floats your boat. The API between both components is specified and so the software side on the ZAP does not need to bother with Zigbee communication states but can act on a
