[已解决]（esp32c3）eddystone url 用 coded phy 可以吗？

[666hjk]

有那位可以帮帮忙？ 谢谢。

1) 构建后的输出 build and flash giving output :
E (356) EDDYSTONE_DEMO: app_main set prefered default phy failed: ESP_ERR_INVALID_STATE
问题在哪里？

2) 把 esp_ble_gap_set_prefered_default_phy( ESP_BLE_GAP_PHY_CODED_PREF_MASK, ESP_BLE_GAP_PHY_1M_PREF_MASK) 这样用法对吗？ 有案例我可以参考吗？

构建后的输出 after build & flash, (see below) ：

E (356) EDDYSTONE_DEMO: app_main set prefered default phy failed: ESP_ERR_INVALID_STATE

[ESP_XuLZ]

coded phy 的使用示例可以参考这个 demo: https://github.com/espressif/esp-idf/tr ... /multi-adv

esp_ble_gap_set_prefered_default_phy API 的使用位置也不对，应当在 controller init 和 enable 之后； 使用 coded phy 广播可以不用这个 API，参考 ble_50/multi-adv 例程进行修改

[666hjk]

谢谢你的提议。

1）我是想, 如果只有一个adv的话， 可用另一个方法来广播而不需要用multi-adv.
2) ble_50/multi-adv 里，.tx_power = EXT_ADV_TX_PWR_NO_PREFERENCE , 他的type 是 uint8_t . 如果用 +126dBm , 就是 0x7E ?

让我做修正，才让你知道。

ESP_XuLZ ,
你提议的demo 是用 ESP-IDF Release v4.3.4 。 我的version ESP-IDF v4.4.2-dirty

1） documentation 里， 用以下方法做跟换对吗？ （我第一次换version, 不怎么会）
cd $IDF_PATH
git fetch
git checkout release/v4.3.4
git pull
git submodule update --init --recursive


2） 如果，每个使用示例 都用不同的version 不就很麻烦？有更好的方法吗？


谢谢。

https://github.com/espressif/esp-idf/tr ... /multi-adv，
multi-adv demo 在很多分支中和 tag 版本都有的， 建议你目前使用稳定的 release/v4.4 分支进行开发

关于版本分支切换后，可以在 esp-idf 目录下如下操作
git submodule update --init --recursive
./install.sh
. ./export.sh

1） 做了以下的步骤，但 version 还是 ESP-IDF v4.4.2-dirty. 需要先清除esp-idf folder理的文件，才跟步骤吗?
~/esp/esp-idf $ git submodule update --init --recursive
~/esp/esp-idf$ ./install.sh
~/esp/esp-idf$ . ./export.sh

2） 电脑里的 components/bt/host/bluedroid/api/include/api/esp_gap_ble_api.h 也找不到修改后的
#define EXT_ADV_TX_PWR_NO_PREFERENCE (127)
- // Copyright 2015-2016 Espressif Systems (Shanghai) PTE LTD ， 还是2016

我有忽略其他的程序吗？ 谢谢。

[ESP_XuLZ]

漏了一条，先切换到 release/v4.4 分支后，再执行后面的操作
cd $IDF_PATH
git fetch
git checkout release/v4.4
git pull
git submodule update --init --recursive
./install.sh
. ./export.sh

1) version 的问题已经搞定。 >> ESP-IDF v4.4.2-378-g9269a536ac-dirty 。 谢谢。
2) build and flash 后的输出也一切ok（看下方）， 但手机scan 不到 eddystone url ？？ 问题在哪里？

广播结构不对

multi-adv demo 只修改如下内容再试下
static uint8_t raw_scan_rsp_data_coded[] = {
0x02, 0x01, 0x06, // ( type of flag )
0x03, 0x03, 0xAA,0xFE, // length of service list , service list , eddystone ID , (16-bit uuid type)
0x03, 0x16, 0xAA,0xFE, // length of service data , service data , eddystone ID , (type of service data)
0x0e, 0xFf, 0x03,'r','b','.','g','y','/','p','z','g','j','7','r' // with url shortener
};

可以网上找下 BLE 广播结构参考下，如 https://www.cnblogs.com/debugdabiaoge/p/15772546.html ，广播结构不正确，手机会过滤掉这些广播不显示

ESP_XuLZ ,

搞定了！ 谢谢你。一天都亮了。

问题在 1）用scan response data
2) service data 的 长度 应该是 0x12
3) eddystone url frame 是 0x10

如果这eddystone url 广播要用中文名， scan时能用中文字显示在手机上吗？
