where to put certificate in enterprise wifi

[mainul]

I am using the "SendDataOverMqtt" example. It is working well with my wifi. But now i have to use it in enterprise wifi. I have certificate file in .pem  format. but I am not where and how to put it. From the not of  WLAN_Enable() function, I found this:

If setup->IsHostPgmEnabled was enabled at the time of WLAN_Setup, then WLAN chip programming for dummy 

 certificate will be enabled (programmed) as well.WLAN_Setup must have been successful prior.This is a blocking call and will 

 connect to the WLAN network.Do not call this API more than once.For enterprise connection (IsEnterprise-true), wifi 

 connection can be authenticated (EnterpriseAuth-true). For WiFi connection authentication, ensure certificate is stored in 

 WiFi chip as /cert/ca.pem

Should I make a cert folder and put the .pem file in as ca.pem ?

Hello mainul,
this certificate is loaded into the XDK using the SD card.

Hi, 

So I made a cert folder in the root of sd card and put the ca.pem file in that folder. Then followed the instruction of this page (from bosch site). 

I exported the WiFi_firmware_update.zip and first flash and run the WifiHostProrammer. This output the messages "writing certificate /cert/ca.pem...file write complete" message. So this means the wifi module has been upgraded and the certificate has been read successfully. Then I flash and run the EnterprizeWifi. But the connection to the wifi is not established. Also no error messages.  

What might go wrong?
