Install & use
Let AI help you install
Connect the device and give AI the detection results together with this firmware information.
1
Confirm the device and connect USB
USB chip information cannot distinguish monochrome from four-color screens. Confirm the model first.
Connect USB and detect the device
Read the chip and capacity first, so AI needs fewer follow-up questions.
Detection may restart the device into download mode. It does not flash firmware; you still need to confirm the display model.
Not detected yet. You can also copy the task first and ask AI to help connect.
2
Give the installation task to AI
Codex on your computer can install dependencies and run programs locally.
What AI will do next
Check compatibility → Prepare firmware and a full backup → Assist with local installation → Verify first run
After copying, start a new chat in Codex on your computer and paste the task.

NOTE4 / NOTE4C · ESP32-S3 / 16 MB Flash · ESP-IDF 6.0 · USB-C data cable · Wi-Fi
Back up and build the application firmware
Preserve a full Flash backup and verify the existing partition layout and recovery path. No GitHub Releases package is currently available. Build the ESP32-S3 application in firmware with ESP-IDF 6.0 following the README. The author specifies application-only flashing at 0x20000, preserving the existing bootloader and partition table. This is not a full image for 0x0 and must not be applied to an unverified partition layout.
Pair a phone and configure Wi-Fi
Hold the round button for about 2 seconds, join QuranTrix-Setup, open http://192.168.4.1 and enter the displayed pairing code. Set home Wi-Fi, location, time zone, calculation method and Asr option. Offline setup supports built-in cities or manual coordinates.
Confirm the panel model and test operation
The application supports both panels but cannot detect them: Auto assumes NOTE4C. On monochrome NOTE4, select NOTE4 black & white in Settings → Look → E-paper model, save and restart. Verify location, time zone and prayer times before testing radio and NFC.

Frequently asked questions
Is this a local-push plugin?
This is standalone community firmware that replaces the device system. It does not run through the official local-push SDK or ZECTRIX Cloud Open API. Radio, online place search and data updates need their corresponding network services. The source is MIT-licensed, retaining notices for Karim, Tomasz Fiedoruk and third-party components.
What do the image and review cover?
Interface sample from the author’s repository, not a device photo. Dates, location and prayer times are illustrative. Source, dual-model implementation and author images reviewed; build, flashing and hardware not independently tested
