How to Adapt Applications for Q1 (4G) Devices

From wizarPOS

Overview

Applications designed for earlier versions of Android or non-4G Q1 terminals need to be debugged for the Q1 (4G) terminal, which runs on Android version 7.0.

Common Issues and Solutions

  1. Library Compatibility Issue:
    • Problem: Error message "dlopen failed: library 'libwizarposHAL.so' not found".
    • Solution: Contact WizarPOS for support. The 'libwizarposHAL.so' library is incompatible with Q1 (4G) and needs to be replaced with 'libwizarposdriver.so'.
  2. Compiled SO Files Usage:
    • If your application uses compiled SO files, update your project with the JNIInterface and SO files from the latest APIDemo.
  3. MAC Address Randomization in First Batch of Q1 Terminals:
    • Note: The MAC address of the initial batch of Q1 terminals is random. This means the Bluetooth address updates every time the terminal restarts.
