Installing APRS Chat Debug (Android)

APRS Chat Debug is a small, temporary tool for diagnosing Bluetooth (BLE) connection problems with Benlink / Benshi radios (VGC VR-N7500, VR-N7600, UV-Pro, GA-5WB, etc.).

Its only job is to reproduce the radio connection, capture a detailed debug log of every step, and let you email that log to the developer. It uses the exact same Bluetooth code as the full APRS Chat app, so whatever fails here fails there too.

It installs alongside the normal APRS Chat app — they don't conflict.

HAMAPI Protocol Reference (BETA)

Overview

HAMAPI is a callsign watchlist and notification service for APRS. It lets users subscribe to callsigns they want to monitor and receive periodic APRS message notifications when those callsigns are active on the network.

What it does:

Investigation Report: Volume Migration Failures — NetApp REST Client Session Race

Summary

Sustained volume migration failures (InvalidVolume: volume is not assigned to a host) affecting 60,000+ operations over 7+ days. Root cause identified as a race condition in the NetApp REST client session handling. A fix has been deployed to QA.

Symptoms

• Error: cinder.exception.InvalidVolume: Invalid volume: volume is not assigned to a host
• Operation: volume_migrate (specifically native_cross_vc_migrate_volume → _migrate_unattached → get_file_sizes_by_dir)

# ILI9486.py — MHS35b/MHS35 variant (Pi 5 compatible, lgpio)
#
# Original: SirLefti/Python_ILI9486 (Waveshare)
# Modified: craigerl/hemna — MHS35b/MHS35 support + Pi 5
#
# Key differences from original:
#   - Uses lgpio (Pi 5 compatible) instead of RPi.GPIO
#   - regwidth=16: commands AND register data sent as [0x00, byte] pairs
#   - Pixel data (bulk framebuffer writes) sent as raw bytes
#   - Pixel format: RGB565 (0x55) instead of RGB666 (0x66)

# ILI9486_MHS35b.py — MHS35b variant support for Python_ILI9486
#
# Drop-in subclass of ILI9486 that provides:
#   1. MHS35b-specific init sequence (manufacturer registers, power/VCOM tuning)
#   2. RGB565 pixel format (16-bit) instead of RGB666 (18-bit)
#
# Usage:
#   from ILI9486_MHS35b import ILI9486_MHS35b, image_to_data_565
#   spi = SpiDev()
#   spi.open(0, 0)
