Sleep Modes

Sat, 2021-01-16 14:37 -- Subramanyan


I am using DA14695 Dev Kit and WiRa SDK 10.440.8.6 using FreeRTOS.

I am implementing a solution to put device to sleep when there is no activitity and have the following questions.

1. Does the call "pm_sleep_mode_set(pm_mode_extended_sleep);" suspend the FreeRTOS tasks ?

2. If we need to reduce the power consumption during sleep, is there a FreeRTOS function that will put the Dialog in the correct sleep mode, suspend the tasks, stop the Bluetooth acitivity, etc ?

Cannot use breakpoint debugging

Fri, 2021-01-15 03:06 -- hjhjlll

Hi PM_dialog,

I created a new project of my own, and now it can’t run after I hit the breakpoint, and it can’t stop. If I click the suspend button and it can’t stop, it will pop up "interrupt failed" and it can’t run to the first I created. A task callback function entry, it seems that the program is running away. What is the problem?

In addition, what does attach mode mean?

BIderectional communication between the GATT client and the GATT server

Tue, 2021-01-12 08:46 -- prasanna

Hello Dialog,

I am testing the examples BLE_central and the DA1469x_Custom_service example to read and write some data between the devices. I can read and write the data from central to the peripheral. In the same way, I want to read from and write to the central from the peripheral.

1. For this, as far as I understand, I need to define the services and characteristics in the BLE_central as well. Is this correct since we can make use of  gattc_read and gattc_write api's with connection index and handles as argments?

Confusion in Properties permission in the DA1469x_Custom_BLE_Service example

Fri, 2021-01-08 13:39 -- prasanna

Hello Dialog,

I am testing the examples "BLE_Central" and the "DA1469x_Custom_BLE_Service" to achieve some communication between the GATT client and server. In the custom service example, in the peripheral_task.c, there are two services defined with one and thee characteristics respectively. Here, I have set some random permissions for the characteristics of the both services. Please find the log file attached below.

Hello Dialog,

it would be great if you could help me with a problem related to sleep and waking-up. 

I have configure sleep mode and waking up through wakeup controller with GPIO 0_12. bur i'm not able to verify that device is going to sleep mode or not i have tried to measure current consumption also but not seeing any change in current.

main.c, sys_init(),
