That didn't even cross my mind 😳
Did you have any of the same issues I had with invalid commands? I'm really banging head against the wall on this
It would be debian jessies py version as it installs 2.7 on ubuntu 14.
As threatened, I've cobbled together a soup-to-nuts procedure to outfit an Arduino running BrewPi (an UNO R3, in this case) with Wifi capability, replacing the USB tether.
Much of this is predicated on turning an esp-03 module into something actually useful. If one starts with a more robustly constructed esp module, a lot of that will have been done already.
And as far as I can tell, pretty near any esp8266 module can be made to work. Some need more bits and pieces added than others, and it's very important to know if a module comes with a 5V to 3.3V regulator (can't really do this easily without it), but otherwise it should work.
The forums have a 30 day expiration for editing your own posts so if anyone finds something that needs fixing let me know. After 30 days, I'll have to appeal to a higher authority, and ain't nobody got time for dat
Wifi-Serial Module for BrewPi
Hardware needed:
- esp8266 module
I used an ESP-03 purchased from here: http://www.amazon.com/gp/product/B00OSWGA8M/?tag=skimlinks_replacement-20 for $7.80 delivered (Prime). This is a minimal ESP8266 implementation and lacks a 5V to 3.3V regulator, as well as header pins. As we'll be using this module on a 5V-based Arduino, a 3.3V supply has to be provided somewhere.
View attachment 321607
Alternatively, there are ESP8266 modules on the market with full IO breakout headers and integrated 5V to 3.3V regulators that can spare the need for soldering.
- FTDI USB-Serial Convertor Module
Genuine FTDI-chip module purchased from here: http://www.amazon.com/gp/product/B00HSX3CXE/?tag=skimlinks_replacement-20 for $6 delivered (Prime). Without this item, you'll need to come up with an alternative method to load the ESP8266 firmware needed to act as a transparent network-serial bridge.
View attachment 321608
- mini USB plug to USB A plug cable (to connect FTDI module to USB host)
- Dupont jumpers
- (2) 1K 1/8-1/4W axial lead resistors
- (1) 2K 1/8-1/4W axial lead resistor
- header
- the minimum number of pins needed is 7
- I cut up a header strip to make a 2x8 header
Optional:
- ld1117v33 fixed 3.3V output LDO regulator
- (2) 1uF 10V or higher capacitors
- 5VDC power supply (eg: wall-wart)
- LEDs for Power and CONN status
- 200-300 ohm resistors for LEDs
Firmware:
- esp-link
I used Release 1.0.4 available here: https://github.com/jeelabs/esp-link/releases/tag/v1.0.4
Download esp-link.tgz for the .5MB flash on ESP-03
- BrewPi AVR hex file: I've used both 0.2.4 and 0.2.10 successfully
Software:
FTDI driver:
- Drivers for FTDI adapters are available here: http://www.ftdichip.com/Drivers/VCP.htm
Specifically, I used the setup executable from here: http://www.ftdichip.com/Drivers/CDM/CDM v2.12.10 WHQL Certified.exe
Execute the file and it will install automagically.
ESP Flasher Utility:
- I used XTCOM_UTIL on Windows, zip file available here: https://drive.google.com/folderview?id=0B3dUKfqzZnlwRXBnV2NzUUNJUms&usp=drive_web
This just needs to be unzipped, then run the executable directly.
Terminal Emulator for Raspbian on Raspberry Pi (optional, for testing):
- I used Minicom
- Install minicon on RPi:
- $ sudo apt-get update
- $ sudo apt-get install minicom
Assumptions:
- Running Raspian Wheezy
- If using Jessie, references to the /var/www/brewpi folder change to /var/www/html/brewpi
- Arduino UNO R3 or equivalent up and running BrewPi on a USB port or Bluetooth module
- An available computer/tablet/phone with Wifi capability and a web browser
Wiring the ESP-03
For a minimal implementation, follow the wiring diagram below. Provide header connections for 5VDC, GND, RX, TX and RESET. Also, provide an extra GND header pin to allow connecting RESET/GPIO0 to GND for programming the ESP.
Note the resistor divider on the RX input. This shifts an incoming 5V-derived TX signal to a compatible level for the 3.3V RX input on the ESP8266, allowing safe connection to a 5V Arduino.
Also, I show a 1K pull-down resistor for GPIO15, but this can be omitted and a straight connection from GPIO15 to GND used instead. However, this would pre-empt using any of the ESP-Link modes that use GPIO15.
View attachment 321610
I built this module on a 2" x 1-1/8" piece of 100mil perf board. I provided three LEDs (for Power, CONN and SER status), and brought out all of the ESP8266 IO pins to the 18 pin header, along with extra GND pins and the inputs to the LEDs. This allows me to configure the module to use any of the ESP-Link modes by using Dupont jumpers.
As all of my UNOs are equipped with home-made LCD shields with provision to connect 3.3V Bluetooth Serial modules, they already have a level-shifter for the outbound TX signal, so I omitted that from my ESP boards.

- GPIO14 = SER LED output (active LOW, connect LED anode to 3.3V)
- GPIO13 = ISP
- esp-01 (AVR) RECOMMENDED
- GPIO0 = hardware Reset output than can be used to reset the Arduino
- GPIO2 = CONN LED output (active LOW, connect LED anode to 3.3V)
- wifi-link-12:
- GPIO0 = CONN LED output (active LOW, connect LED anode to 3.3V)
- GPIO1 = ISP
- GPIO2 = SER LED output (active LOW, connect LED anode to 3.3V)
- GPIO3 = hardware Reset output than can be used to reset the Arduino - GPIO13: connect to TX of microcontroller

- on this page you can change the ESP8266 serial port baud rate to match up with the target device
- when connected to an RPi, be sure to match the terminal emulator command with the baud rate setting
- I did my testing on the RPi at 115200 baud without issue
- when connected to an UNO running BrewPi, set the baud rate here to 57600.
Optional: Testing the ESP using an RPi
This procedure can use any ESP-Link mode other than wifi-link-12 (that mode uses different GPIO pins for RX/TX).
- Jumper ESP-03 pins
CH_PD 3.3V
GPIO15 1K Pull Down
- Wire ESP to Raspberry Pi
- ESP VCC to Raspberry Pi 5V
- ESP GND to Raspberry Pi GND
- ESP RXD to Raspberry Pi (GPIO14, Pin 8)
- ESP TXD to Raspberry Pi (GPIO15, Pin 10)

- Power-up the ESP
- Power-up the Raspberry Pi
- Connect to the ESP network port
- using Putty, Telnet to IP Addressort 23 (eg: 192.168.1.230:23)
- Putty settings:
- Terminal
- disable Implicit CR every LF
- enable Implicit LF every CR
- Local echo = Force On
- Local line editing = Auto
- On Raspberry Pi, connect to serial port
- I use Putty from my Windows system to log into the R'Pi, then run minicom to connect to the serial port
- pi@raspi2 ~ $ minicom -b 115200 -o -D /dev/ttyAMA0
- Now you can type in either terminal session to push data back and forth

Programming Arduino with avrdude
avrdude does not recognize "socket://192.168.1.230:23" for a port definition, so you can't flash the BrewPi hex file directly from within the BrewPi gui.
Instead, open a terminal session and run avrdude manually using the following command format (note that this is a single long-assed command!)
Code:$ sudo /usr/share/arduino/hardware/tools/avrdude -F -e -p atmega328p -c arduino -b 115200 -P net:192.168.1.230:23 -U flash:w:"brewpi-arduino-uno-revC-0_2_10.hex" -C /usr/share/arduino/hardware/tools/avrdude.conf
Be sure to use the full path to the hex file!

If I close maintenance panel and restart the script, no temperature is detected. Is this because brewpi needs 2 sensors detected to work?
I don't think so, do you see the temp in the maint panel when you detect devices? Do you see the communication for the device changes you make in the log file?
The last temp sensors I purchased, one of them reports 85c until it's had power for a minute, it's quite odd as none of the others have.

This is the setup so far. Only the 3m one wire temp probe arrived. I ordered 1x 3m for the fermenter and 5x 1m from different supplier on eBay.
So I can go into the device list and the probe is detected.

I can apply "Beer Temp" to it.
If I close maintenance panel and restart the script, no temperature is detected. Is this because brewpi needs 2 sensors detected to work?
While you won't be able to run a Beer Constant or Beer Profile, if you set your one probe to be the Chamber Temperature probe, I bet you can run in Fridge Constant mode, fwiw...
