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......

Why switch off BLE?

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.

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)?

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.

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?
