BLE Data Throughput Issue - STM32WB5MMGH

LR.2
Associate III

Hi,

I have been using STM32WB5MMGH for transmitting PCM Data. I used BLE data throughput method from the example code for transmitting data. Audio sample rate is 8000 Hz, that 8000 data is transmitted in a buffer size of 244. The sample is of 16-bit in 244 size buffer we have only 122 data. When I started transmitting and converted the PCM data to .wav in the computer there are some clipping noise means some portions of audio is not there. Then I started transmitting none values from 1 to 100. Now I confirmed data is not properly transmitted there is some kind of data loss. 

Then I found that BLE status is BLE_STATUS_INSUFFICIENT_RESOURCES. Because of these that data loss is happened. How can I able to correct this.
