Yay, WiPhone!

Be cautious charging the WiPhone on a Xiaomi Mi Power Bank 3 Pro

xopr's WiPhone broke down: his guestimates are that the device in USB-A port 1 that supported adaptive charging might bring the second USB-A port to 9V or 12V (out of spec), which in this scenario will fry the CP2104 USB-UART chip when you would plug it in second, no matter how short the time frame would be.

custom firmware

you can use the ACKspace modified firmware by setting https://ackspace.nl/WiPhone/WiPhone.ini into the ota.ini file (or via the telephone) Current applied patches:

• LoRa 868MHz
• ackspace.nl fake NAPTR (hardcoded IP)
• fix fiddly unlock (mentioned here)

Work in progress:

• LoRa menu (currently crashes the phone, don't use)

notes

• read documentation here
• report bugs at https://github.com/ESP32-WiPhone/wiphone-firmware/issues
• enable/disable automatic firmware settings at Menu » Settings » Firmware settings
• before you use LoRa, make sure to edit Hardware.h, look for RF95_FREQ and set it to 868MHz for EU:

#define RF95_FREQ 868.0 (See this (somewhat sparse) issue)

• enable UDP by adding u=UDP_SIP to an account in data/sip_accounts.ini (not yet tested)
• Test LoRa functionality with (upcoming change for) OpenMQTTGateway

Get started

• download source code
• run V="0.8.30"; unzip WiPhone-$V && rm -fr WiPhone && mv WiPhone-$V WiPhone
• open WiPhone/WiPhone.ino using Arduino
• once: set up IDE (see documentation for details):
  • Open preferences (CTRL+,) and add https://wiphone.io/static/releases/arduino_platforms/package_WiPhone_index.json (comma separated) into Additional Boards Manager URLs
  • go to Tools » Boards » Board Manager and install WiPhone
  • Arduino option Tools » ESP Sketch Data Upload: download ESP32FS-1.0.zip into the ~Arduino/tools directory with mkdir -p ~/Arduino/tools && unzip ESP32FS-1.0.zip -d ~/Arduino/tools
  • TODO: esptool.py serial: sudo pip install pyserial (check your default python version)
• Select Tools » Boards » Wiphone » Wiphone arduino
• compile with (CTRL+r)

custom mods

command line build

The provided repo contains several patches and a semi-automated build/upload process to create your own custom binary (without opening the Arduino IDE) This includes:

• caret cursor color fix
• lockscreen fix (mentioned here as well)
• LoRa 868MHz, menu is WIP
• ackspace.nl fake NAPTR (hardcoded IP)
• loudspeaker fix (mentioned here)

5V injector

To charge the Wiphone (with 5V, including charging indicator), without using USB (since xopr's UART is broken), he soldered 2 cables with female dupont ends to the 5V rail (not VBUS). With troubleshooting, he also noted some useful pads/components, more or less reversed engineered: File:Wiphone testpads components.svg

Here is the result

• 

  Ground on the bottom pad indicating "-" 5V on the left side of the "big" resistor above the right pogo header (not yet done in the picture) Dabbed in hot glue on the solder joints and strategically slightly right/above the center polycarbonate bridge (not in picture)

• 

  Wifi antenna cover just fits on top. Dabbed in hot glue: strategically slightly right/above the center polycarbonate bridge

• 

  Female dupont connectors fit nicely through the QWIIC slot on the LoRa daughter board.
