From f97a2d15186b9612359baacdf29533b8e41c1258 Mon Sep 17 00:00:00 2001 From: Valentin Squirelo Date: Fri, 18 Jul 2025 13:22:39 +0200 Subject: [PATCH 1/6] Add Joy-Con 2 support This commit introduces functionality to detect and handle Joy-Con 2 devices in the Bluetooth firmware. It includes manufacturer ID checks, GATT characteristic discovery, and IMU sensor enabling commands. Additionally, a stub for report decoding is added, with logging for detected devices and commands sent. This enhancement allows for better integration and handling of Joy-Con 2 controllers. --- firmware-bluetooth/src/main.cc | 132 ++++++++++++++++++++++++++++++++- 1 file changed, 130 insertions(+), 2 deletions(-) diff --git a/firmware-bluetooth/src/main.cc b/firmware-bluetooth/src/main.cc index 913618aa..42a44071 100644 --- a/firmware-bluetooth/src/main.cc +++ b/firmware-bluetooth/src/main.cc @@ -1,5 +1,6 @@ #include #include +#include #include #include @@ -275,6 +276,39 @@ static void clear_bonds_work_fn(struct k_work* work) { } static K_WORK_DEFINE(clear_bonds_work, clear_bonds_work_fn); +#define JOYCON2_MANUFACTURER_ID 0x057E +#define JOYCON2_LEFT_NAME "Joy-Con (L)" +#define JOYCON2_RIGHT_NAME "Joy-Con (R)" + +static bool is_joycon2_device(const struct bt_scan_device_info* device_info) { + // Check manufacturer data + const struct bt_data* adv = device_info->adv_data; + size_t adv_len = device_info->adv_data_len; + size_t i = 0; + while (i + 1 < adv_len) { + uint8_t len = adv[i]; + if (len == 0 || i + len >= adv_len) break; + uint8_t type = adv[i + 1]; + if (type == BT_DATA_MANUFACTURER_DATA && len >= 3) { + uint16_t company_id = adv[i + 2] | (adv[i + 3] << 8); + if (company_id == JOYCON2_MANUFACTURER_ID) { + return true; + } + } + if (type == BT_DATA_NAME_COMPLETE || type == BT_DATA_NAME_SHORTENED) { + char name[32] = {0}; + size_t name_len = len - 1; + if (name_len > sizeof(name) - 1) name_len = sizeof(name) - 1; + memcpy(name, &adv[i + 2], name_len); + if (strstr(name, JOYCON2_LEFT_NAME) || strstr(name, JOYCON2_RIGHT_NAME)) { + return true; + } + } + i += len + 1; + } + return false; +} + static void scan_filter_match(struct bt_scan_device_info* device_info, struct bt_scan_filter_match* filter_match, bool connectable) { char addr[BT_ADDR_LE_STR_LEN]; @@ -286,6 +320,11 @@ static void scan_filter_match(struct bt_scan_device_info* device_info, struct bt bt_addr_le_to_str(device_info->recv_info->addr, addr, sizeof(addr)); LOG_INF("%s address: %s connectable: %s", __func__, addr, connectable ?
