ble-gatt-integration

ble-gatt-integration is a skill for Claude Code, Codex from easyzoom/aix-skills. It costs 37 tokens per session (691 once invoked), scanned A, original, MIT.

Guidance for building and troubleshooting Bluetooth Low Energy GATT services. GATT is the part of Bluetooth that defines discoverable data services, characteristics, permissions, and data exchange.

In plain words
What is it for?
Use it to design or debug services, reads, writes, notifications, indications, subscriptions, pairing, MTU limits, and transfer speed.
Why use it?
It separates connection, permissions, security, packet size, and data-flow problems that can otherwise look like general Bluetooth failures.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ble-gatt-integration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

BLE GATT Integration

Overview

Use this skill to debug BLE GATT by separating advertising, connection, discovery, attributes, permissions, MTU, security, and data flow. GATT failures are often permission or state-machine mismatches, not radio failures.

When To Use

Use this skill when:

  • The user is creating or debugging BLE services, characteristics, descriptors, notifications, indications, reads, writes, or subscriptions.
  • The issue involves missing services, write failures, CCCD problems, MTU, data truncation, pairing, bonding, connection parameters, or low throughput.
  • The stack is Zephyr, ESP-IDF, nRF Connect SDK, NimBLE, BlueZ, Android, iOS, or a vendor BLE SDK.

Do not use this skill when the device cannot advertise or connect at all. Start with platform-specific radio and controller bring-up first.

First Questions

Ask for:

  • BLE stack, device role, central/client app, peripheral firmware, and logs.
  • Advertising data, connection status, service UUIDs, characteristic UUIDs, and properties.
  • Attribute permissions, security level, pairing/bonding state, and CCCD state.
  • MTU, connection interval, PHY, data length extension, and payload size.
  • Sniffer trace or client error if available.

Debug Workflow

  1. Prove discovery. Confirm advertising, connection, primary service discovery, and attribute handles using a known BLE client.

  2. Check attribute contract. Verify UUIDs, properties, permissions, descriptors, lengths, and endian/unit conventions.

  3. Separate reads, writes, and subscriptions. Test read, write-with-response, write-without-response, notify, and indicate one at a time.

  4. Validate security. Match permissions to pairing, bonding, encryption, MITM, and key storage.

  5. Tune transport parameters. For throughput, check MTU, connection interval, PHY, data length, buffering, and application pacing.

  6. Test client diversity. Compare behavior on at least one generic tool and the real Android/iOS/client app.

ble-gatt-integration is a skill published in the GitHub repository easyzoom/aix-skills (31 stars, last pushed 1mo ago), licensed MIT. It adds 37 tokens to every session and 691 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
