👑 hackrf_biast — the antenna power utility, bestie edition

✨ NAME ✨

hackrf_biast — antenna power utility 🦋

---

🌸 DESCRIPTION 🌸

ok so hackrf_biast is the HackRF antenna power bias-T configuration utility. that's the whole vibe.

it lets you enable/disable antenna power on the HackRF for compatibility with software that does not support this function. so like, if your software is being a little bit oblivious to the bias-T situation, you just handle it yourself here. main character energy fr fr.

Usage:

-h, --help: this help

-R: Reset all bias tee settings to device default.  When combined with
       -r/-t/-o, those settings will take precedence.

-b: <mode> : 1=Enable bias tee immediately, 0=disable immediately

-r: <mode> : Set default bias tee power when device enters RX mode

-t: <mode> : Set default bias tee power when device enters TX mode

-o: <mode> : Set default bias tee power when device enters OFF mode

-d:  <serial_number>: Specify serial number of HackRF device to
       configure.

let's break those down one by one because you deserve the full tea ☕

• -h, --help — prints this help. iconic, we love a self-aware king 🫶
• -R — Reset all bias tee settings to device default. ⚠️ but listen: when combined with -r/-t/-o, those settings will take precedence. so -R doesn't get the last word if you also pass the others, no cap.
• -b <mode> — 1 = Enable bias tee immediately, 0 = disable immediately. instant gratification, we love that for us ✨
• -r <mode> — Set default bias tee power when device enters RX mode 📡
• -t <mode> — Set default bias tee power when device enters TX mode 📶
• -o <mode> — Set default bias tee power when device enters OFF mode 💤
• -d <serial_number> — Specify serial number of HackRF device to configure. use this when you've got more than one plugged in and you need to point at the exact one, iykyk 🔥

💖 EXAMPLES 💖

here's the one example, verbatim, because copying it wrong would be a crime:

hackrf_biast -R : Resets biast setting to default.

and here's the important part: the -r/-t/-o options support the following mode settings:

• leave — do nothing when entering mode 🍓
• on — enable bias tee when entering mode 🌈
• off — disable bias tee when entering mode 🌙

so like, leave is the "i'm not touching it, i'm just vibing" option and honestly? respect.
