SPP_BLE_SERVER receive more than 20 bytes data from mobile application

Hello

I am working on SPP_BLE_SERVER example code. I have tested the server and client model and able to receive the 128 bytes but I want to connect the mobile application with SPP_BLE_SERVER and send more than 20 bytes data from mobile application to device.

But when I am sending the more than 20 bytes data from mobile application, device receives only 20 bytes. Instead of 20 bytes I need to receive at least 128 bytes from mobile application.

Mobile application have the support to send more than 20 bytes data. I need to add the support in SPP_BLE_SERVER so that it can receive the data.

Any one help me to configure the SPP_BLE_SERVER example code so that we can receive more than 20 bytes data from mobile application.

Thanks
