Thomas Göttgens 58657d484a Re-enable mbedtls secp384r1 on ESP32 (#11344 )

Let's Encrypt Generation Y chains sign a P-256 leaf with the P-384
intermediate YE1 under ISRG Root YE. mqtt.meshtastic.org switched to
this chain on 2026-07-29. With CONFIG_MBEDTLS_ECP_DP_SECP384R1_ENABLED=n
mbedtls cannot parse the peer chain and the TLS handshake aborts with
MBEDTLS_ERR_PK_UNKNOWN_NAMED_CURVE, breaking MQTT over TLS on every
ESP32 target.

Costs about 4 kB of flash.

Fixes #11316

Meshtastic Firmware

Website - Documentation

Overview

This repository contains the official device firmware for Meshtastic, an open-source LoRa mesh networking project designed for long-range, low-power communication without relying on internet or cellular infrastructure. The firmware supports various hardware platforms, including ESP32, nRF52, RP2040/RP2350, and Linux-based devices.

Meshtastic enables text messaging, location sharing, and telemetry over a decentralized mesh network, making it ideal for outdoor adventures, emergency preparedness, and remote operations.

Get Started

🔧 Building Instructions - Learn how to compile the firmware from source.
⚡ Flashing Instructions - Install or update the firmware on your device.
