tdme_settxpower(9)

💅 tdme_settxpower — the kernel API manual, but make it make sense

okay so bestie, welcome to tdme_settxpower(9) from the Kernel API Manual ✨ this is the little function that sets your tx power for MLME_SET phyTransmitPower, and honestly? she's small but she matters 🎀

---

✨ SYNOPSIS ✨

u8 tdme_settxpower (u8 txp , void *device_ref );

that's it. that's the whole vibe check. two args, one u8 coming back at you 🫶

---

🌸 ARGUMENTS 🌸

• txp — the Transmit Power. yes, that's the whole description. she's a u8 and she's booked and busy 💅
• device_ref — a "nondescript pointer to target device". not mysterious, not fancy, just a pointer that points at the device you're targeting. no cap 🔥

---

💖 DESCRIPTION 💖

okay so the actual tea ☕: the value gets normalised to the 802.15.4 Definition, and that definition is 6-bit, signed. here's the bit map, memorise it bestie:

• Bit 7-6: not used — literally just sitting there, unemployed, iconic of them honestly 🙈
• Bit 5-0: tx power, and the range is -32 - +31 dB 🌈

so like, if you're packing your own bits in there, mind the layout. six bits, signed, that's the moment. periodt. 👑

---

⭐ RETURN ⭐

returns the 802.15.4 status code of api calls — so you get a status code back, go check it, don't just ignore it, i'm begging 😭

ngl bestie, this one's short, but "short" ≠ "skip it". the bit layout is the whole point of the page — if you mess up bit 7-6 vs bit 5-0 you're gonna have a bad time 😭 💀
