Problem with Communicate BLE and WiFi using one UART?

[vishal]

Hi,

I am developing application using nRF52832, s132, sdk13.2 which is collect sensor data and sent it to server. I have sent data to server using nRf52832 and interface with wifi module via UART. Now problem is i want to configure WiFi module credentials using BLE with android app, when i connect BLE to android app and sent wifi credentials to nRF52832 chip store it in one buffer and OFF BLE trying to switch this same UART for WiFi communicating. But at this time my hardware is reset and this credentials buffer is empty. So sir how i can communicate with BLE and then off this BLE connection switch to WiFi using only one UART. Please give me some example code and reference tutorial which is useful for me. '

Thanks......

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?

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........

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

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...

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.
