你好，请问下我在用DA14682蓝牙大量数据长时间持续发送数据的时候。前面20分钟正常。20分钟后遇到函数返回的BLE_ERROR_BUSY状态，且每次发送数据都会遇到。请问这是怎么回事？
我用的demo是ble_sps_peripheral
问题出现在函数：ble_gatts_send_event里的ble_mgr_gatts_send_event_cmd_handler里的BLE_ERROR_BUSY
/* Check if GATT controller is busy */
if ( ke_state_get(KE_BUILD_ID(TASK_GATTC, cmd->conn_idx)) & GATTC_SERVER_BUSY ) {
ret = BLE_ERROR_BUSY;
goto done;
}
我每次蓝牙发送数据前会检查上一次蓝牙发送数据时候完成。若上一次蓝牙发送完成这次发送才能开始。

Hello Dialog,
I have a customized board with DA14680 and some sensors. When not in use, I use a button to trigger the wakeup and put board to hibernate mode. However, the MCU wakes itself up after 1 minutes. I have a few questions:
1. what is the correct way to put system to hibernate mode? Is it simple as "pm_set_sleep_mode(pm_mode_hibernation);", then whenever system is in idle (not running any active task), it will go hibernate?
Dear Dialog Team,
I uploaded the code Ble adv (DA1468x_DA15xxx_SDK_1.0.14.1081) in USB development kit (DA14683) and I open the app (made by - bluepixel tech) on my android phone but no device is showing on my app. Why?
waiting for your quick response
Hi,
Using a Dialog ProKit with a DA14681 daughter board and DA1468x_DA15xxx_SDK_1.0.14.1081.
I have modified the freertos_retarget project to experiment with UART2 for communication with another processor. I monitor the output transmit signal with a scope. The relevant code fragments are below.
UART_BUS(UART2, SERIAL2, HW_UART_BAUDRATE_1000000, HW_UART_DATABITS_8, HW_UART_PARITY_NONE,
HW_UART_STOPBITS_2, 0, 1, HW_DMA_CHANNEL_3, HW_DMA_CHANNEL_2, 0, 0)

Hello Dialog Team,
I am using DA14583 Bluetooth mesh to implement a home automation project.
One of the nodes in this mesh is going to be an esp32 (https://www.espressif.com/en/news/Espressifs_BLE_Mesh_SDK_Is_Now_Bluetooth_SIG_certified). Any specific configuration I need to set to include esp32 in the mesh or its the same configuration of including another dialog ble device.
Hello Dear Support,
I've downloaded "DA1458x_DA1468x_PLT_v_4.3.0.310.zip" and "DA1468x_DA15xxx_SDK_1.0.14.1081.zip" and tried to build the Production Test for DA14861 without any success. Could you please help me to find the right project and source files in order to build the Production Test for DA14861.
Thanks in advance,
Ron.
Hello!
Does your “DA14682” support “Bluetooth long range”?
We're looking for a bluetooth 5 chip supports both long range and mesh for our home automation device. Or could you kindly tell me such a model name?
Best regards,
Dear Dialog,
I want upgrade WRBL project SDK 1.0.8 to 1.0.14, but the project uses a modified SDK, I don't know what to modify. Please teach me how to do.
Hello Dialog Team,
I am Getting Error while importing project ("ble adv") from SDK ("1.2DA14682/DA14683 Mesh SDK"). Error is - "Invalid project path: Include path not found (ble_stack)".
