Release 1.0.0

Release with over-the-air (OTA) reflashing of the esp, port 23 transparent bridge as well as AVR & ARM flashing support. Simple debug log page to view the esp-link's own os_printf output via the web and a console page to see the attached uC's output. Buttons to reset the uC and change the baud rate. A pin configuration selector to change GPIO function assignments. Saving of configuration changes in flash.

Changes since v1.0.rc1: fix crash on empty upload request; add wifi channel info

This version uses the Espressif IOT SDK version 1.2.0.

Install via serial upload

The short version for the serial install is:

• flash boot_v1.4(b1).bin from the official esp_iot_sdk_v1.2.0 and included in the release tgz to 0x00000
• flash blank.bin from the official SDK and also included in the tgz to 0x7e000
• flash user1.bin to 0x01000

On Linux using esptool.py this turns into the following:

curl -L https://github.com/jeelabs/esp-link/releases/download/v1.0.0/esp-link.tgz | tar xzf -
cd esp-link
esptool.py --port /dev/ttyUSB0 --baud 460880 write_flash 0x00000 boot_v1.4\(b1\).bin 0x1000 user1.bin 0x7e000 blank.bin

(You can also use a slower baud rate and wait longer...)

Upgrade over-the-air

To upgrade from an earlier version of esp-link:

curl -L https://github.com/jeelabs/esp-link/releases/download/v1.0.0/esp-link.tgz | tar xzf -
cd esp-link
./wiflash <esp-hostname> user1.bin user2.bin

Installing esptool.py

On Linux use esptool.py to flash the esp8266.
If you're a little python challenged then the following install instructions might help:

• Install ez_setup with the following two commands (I believe this will do something
  reasonable if you already have it):

  wget https://bootstrap.pypa.io/ez_setup.py
  python ez_setup.py
  

• Install esptool.py:

  git clone https://github.com/themadinventor/esptool.git
  cd esptool
  python setup.py install
  cd ..
  esptool.py -h
  

Release Candidate 1.0.rc1

This is a release candidate for the "1.0" release.

Release with over-the-air (OTA) reflashing of the esp, port 23 transparent bridge as well as AVR & ARM flashing support. Simple debug log page to view the esp-link's own os_printf output via the web and a console page to see the attached uC's output. Buttons to reset the uC and change the baud rate. A pin configuration selector to change GPIO function assignments. Saving of configuration changes in flash.

Changes since v0.10.3: fix handling of baud rate mismatches; allow uart log to be disabled
