Re: BLE Frequency Hopping

Hello All, I have just installed esp-idf tool chain I have TTGO T-Call ESP32 board with me and i am interested in working with BLE part of the respective board. I have also tried running the basic BLE examples on the board and was able to run them successfully. As per my understanding the frequency...

Re: 配对过的IOS13.5的手机无法连接删除绑定信息的esp32蓝牙

你好,我的IDF版本是4.1,手机是IOS13.5版本的,APP是nRF Connect。 当IOS手机配对连接esp32蓝牙成功后,把esp32本地存储的蓝牙绑定信息删除掉,IOS手机就没办法再次连接了,会提示“Peer removed pairing information”,然后断开。除非用户手动在手机蓝牙设置里把手机本地的设备绑定信息删除后,才能再次配对连接。 目前我测试到IOS11,IOS12版本的手机不会出现这种情况。 我在安卓手机上也复现了同样的问题, 设备使用 public addr,设备与手机进行安全配对后,设备上的 bond 信息被删除后,无法和手机再次建立连接。 我使用...

Re: BLE bonding limit

Hello, Below thread described 15 bonded devices can be stored in ESP32 and it will delete the oldest bonded device to make room for the new one when the device reaches the limit. https://esp32.com/viewtopic.php?t=6403 Is there a way to change the max number of bonded devices? Also, can change the r...

Re: IOS12以上搜索不到蓝牙

Hi liwei,

为了验证设备是否发送广播包: 你可以用 ESP32 设备的 gatt_client demo 同时进行扫描, 将扫描内容打印出来,提供 log 信息给我们。

我复现问题时,有两个疑问:
1. 请问扫描广播包的 app 软件是使用的 nrf_connect app 吗?
2. 广播的设备端使用的是什么程序,以及广播的数据内容是什么?

Re: ESP BLE网格传感器

我想通过将传感器连接到节点之一来将传感器数据泛洪到BLE Mesh网络中的所有设备。我无法理解如何在ESP-IDF的组件中使用传感器服务器和客户端模型,以及如何使用esp32 ble Mesh协议构建传感器网络。 https://github.com/espressif/esp-idf/blob/f91080637c054fa2b4107192719075d237ecc3ec/components/bt/esp_ble_mesh/mesh_models/server/sensor_server.c 1: 你可以参考 https://www.bluetooth.com/specificatio...

Re: Ble mesh provisioner

是的,我从ble_mesh_fast_prov_server demo 代码中找到如你所说的自定义实现方法。我猜测vendor model没有统一的标准,所以各个厂家的做法都不一样?我目前正在把ble_mesh_fast_prov_client demo 按照手机provisioner配置流程去修改,当前已可以实现esp32 vendor model client 和nordic vendor model server通讯了。目前ble_mesh_fast_prov_server 存在vendo rmodel client和server,有没有必要实现ble_mesh_fast_prov_c...
