Did you check out the timer library? There is also a tutorial here.

Just create and start the timer, then call power_manage()/sd_app_evt_wait() to go to sleep.

Sir can you provide me some example sample program for the same to controlling nRF52832 device ON/OFF every 1 hr. Please give some useful and reference tutorial in programming. I am searching lots off but until not find solution.

Thanks in advanced...

Yes. That shouldn't be a problem. Why would you use WDT for that? Can't you just use the timer library?

Thank you so much... Is it any way to write a nordic program for ON/OFF nRF52832 device in every 1Hr. Now i am writing program for wake up my Nordic device every 1 Hr, wakeup only for 10-15sec after again sleep. I am read Watch dog timer and also learn sample example of WDT. But unable to to do the same. Can you sir please provide me some example code and useful tutorial for controlling my device in every 1Hr. Any help really appreciate for me... Thanks........

Android app sends message/data to nRF52 through the BLE channel, and your application logic inside the nRF52 forwards the message/data received on the BLE channel to the wifi module through the UART interface. Have you gone through the tutorial section in this forum?

Now it working but how is it possible to communicate with BLE then WiFI while connected android app with BLE. Means i no need to disable BLE and enable wifi but nRf52832 having one UART it communicate to both BLE as well as WiFi. I am little confuse Can you explain me?

Thanks for help.....!!

Most likely something in your code that's causing the reset. Are you sure you set up the uart correctly i.e. the correct baud rate, enable/disable the h/w flow control?

Thanks for your reply.....Ya write, But whenever i trying to get communicate with wifi while connected BLE with android app my nordic board reseting. Why it so reset is it reset due to communicate with BLE as well as WiFi. I am write function of WiFi config. using AT cmd and call this after send wifi credentials when BLE connected to android.

Is this what you have in mind?

Android phone <-- BLE --> nRF52832 <-- uart --> wifi module

So when the nRF52832 gets the wifi credentials why can't it send the credentials to the wifi module (AT commands through the uart)?

Because once connect android app to nRF52832 BLE send WiFi credentials to nRF52832 and then need to communicate WiFi. I am interface WiFi module using UART. So one UART and two interface 1. BLE 2. WiFi. If i communicate with both at a time WiFi Module is not response proper then hardware is rest.

Why switch off BLE?
