Hi,
I am working on Tm4c129xnczad controller. I am using SPPLE demo program to connect remote Bluetooth. It has Bluetooth address " 30ae7bc71efc ".So i tried to connect the remote Bluetooth using the function such as ConnectLE(NULL);
DiscoverSPPLE(NULL);
ConfigureSPPLE(NULL); so i am getting output as Connection Request successful.
No Device Info in discoverspple.
No Device Info in config.
Can you please tell me why i am not able to connect the remote Bluetooth. I am here by sharing the code please tell me how to resolve the issue.
