From d1e15b928107e2459b65c7a2484517e9e2a830cc Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Dani=C3=ABl=20van=20de=20Giessen?= Date: Tue, 12 Dec 2023 15:56:13 +0100 Subject: [PATCH] extmod/nimble: Enable key distribution to support bonding. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This sets the BLE key distribution parameters at runtime. This isn't needed in most ports since we already set the default values in `extmod/nimble/syscfg/syscfg.h`; however in the ESP32 port that headerfile is not used, and the default values in the ESP-IDF don't enable key distribution nor can we change those defaults via `sdkconfig`. Thus we're setting these values explicitly at runtime.
