connectivity-ble

connectivity-ble is a skill for Claude Code, Codex from beriberikix/zephyr-agent-skills. It costs 66 tokens per session (700 once invoked), scanned A, original, Apache-2.0.

A guide to adding Bluetooth Low Energy wireless communication to devices running Zephyr, an operating system for embedded hardware. It covers advertising, connections, device data services, and reducing radio use.

In plain words
What is it for?
Use it to add BLE communication, define device data services, advertise a device, manage connections, and improve battery life with connection settings and scheduled data sending.
Why use it?
It helps avoid piecing together wireless setup and battery-saving decisions from scattered documentation. The guidance keeps devices connected while limiting power consumption.

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

connectivity-ble 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/ble_timing_helper.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Zephyr Connectivity: BLE

Implement robust, low-power Bluetooth Low Energy applications using Zephyr's industry-standard BLE stack.

Core Workflows

1. BLE Fundamentals

Set up advertising, define GATT services, and manage connections.

  • Reference: ble_fundamentals.md
  • Key Tools: BT_GATT_SERVICE_DEFINE, bt_le_adv_start, BT_CONN_CB_DEFINE.

2. Send-When-Idle Pattern

Optimize radio usage by bundling data and transmitting only during idle periods.

  • Reference: send_when_idle.md
  • Key Tools: k_work_delayable, Workqueues, SMF integration.

3. Power Optimization

Fine-tune intervals and connection parameters for maximum battery life.

Quick Start (Advertising)

CONFIG_BT=y
CONFIG_BT_PERIPHERAL=y
#include <zephyr/bluetooth/bluetooth.h>

void start_simple_adv(void) {
    bt_enable(NULL);
    bt_le_adv_start(BT_LE_ADV_CONN_NAME, NULL, 0, NULL, 0);
}

Professional Patterns (Wireless Design)

  • Aggressive Latency: Increase peripheral latency to allow the radio to stay off longer during quiet periods.
  • Decoupled Messaging: Use Zbus to feed data into the BLE module, keeping the radio logic separate from the application logic.
  • Idle Bundling: Use the "Send-When-Idle" pattern specifically to reduce the number of wake-ups for the radio controller.

Automation Tools

Examples & Templates

Validation Checklist

  • Device advertises with expected name/flags and is discoverable by a BLE scanner.
  • Central can connect, exchange GATT data, and disconnect without stack errors.
  • Configured connection parameters are reflected after negotiation.
  • Send-When-Idle flow batches traffic instead of transmitting every sample immediately.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

connectivity-ble is a skill published in the GitHub repository beriberikix/zephyr-agent-skills (63 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 66 tokens to every session and 700 once invoked, about $0.0003 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.
