Re: BLE距离问题

for(i=0; i<ESP_BLE_PWR_TYPE_DEFAULT; i++){ ret = esp_ble_tx_power_set(i,ESP_PWR_LVL_P7); if (ret) { ESP_LOGE(GATTC_TAG, "%s set ble tx power failed: %s\n", __func__, esp_err_to_name(ret)); return; }else{ ESP_LOGE(GATTC_TAG, "%s set ble tx power success\n", __func__); } } 程序中加入以上代码后,测试距离,没有什么变化啊!!

目前用ESP32-WROOM-32做一个产品,ESP32做BLE的client去连接另一个设备(这个设备与手机通讯时的距离大于30米),发现2者之间的距离只有7~8米,不能满足需求,请问有什么办法可以增加这个距离呢?
Hi, Nick

你可以使用 esp_ble_tx_power_set 来调大发射功率, 使用参数 ESP_PWR_LVL_P7 可以调到最大的 +9dBm.

Re: 贵司的SIG_MESH是否已经出正式版了?

Hi,ESPRESSIF 你的意思是说,乐鑫的IDF4.1版本会包含sig mesh?一个月后(2019年12月)就会发布? Hi, Luhui SIG Mesh 在 IDF 4.0 上已经有了, 只是没有包含所有的功能, 比如有些 Server Models 还没有实现, 其他绝大部分的功能都已经支持了. 完整版的 SIG Mesh 功能 (包含所有的 Features, Server Models, Client Models) 争取在一个月内合到 IDF Master 分支, 也就是最终会体现在 IDF 4.1 上. Thanks, Island Hi,ESPRESSIF 那之前esp...

Re: 贵司的SIG_MESH是否已经出正式版了?

看到贵司发出获得SIG MESH的认证,是否最新的SDK已经包含了SIG MESH的正式版固件? Hi, Luhui 最新的 IDF 4.0 包含了我们主要功能过认证的版本. 完整功能的过认证版本, 还需要等一段时间, 预计 1 个月内会更新上去.

Re: ESP BLE Mesh v0.6 Released, SIG Certified

Great news!!!.Which development board do you suggest as the cheapest for establishing a Ble mesh network for sensor control.I will mention my requirements in brief. The nodes will transfer the sensor data and transmit them to a central node and based on the response from this central node relays ar...

Re: Intermittent sleep without reconnecting BLE

Hi all. I’m developing a device based on ESP32-WROOM-32d. The device acts as a BLE-client and polls the BLE-server(cc2650) every 5 seconds. The rest of the time he sleeps( light sleep ). The problem is that waking up and reconnecting takes a lot of time and the consumption is almost the same as not...

Re: ESP BLE Mesh v0.6 Released, SIG Certified

Hi again Espressif, I continue my development but would like to know if you could provide an example for a proper Sensor Server model, since the API only has direct functions for a SensorClient; my guess so far has been trying the generic ESP_BLE_MESH_SIG_MODEL macro. I have been reading the BT-Mes...

Re: ESP BLE Mesh v0.6 Released, SIG Certified

Hi Espressif, I am trying to build a simple mesh network with 2 ESP32 chips periodictly blinking the leds. One ESP32 is provisioner the other one is node, I use the code ble_mesh_provisioner and ble_mesh_node examples. For the provisioner, I tried to create a new task in app_main() after the ble_me...
