CCS/CC2640R2F: CC2640R2F

Tool/software: Code Composer Studio

Hello All,

I am working on SIMPLELINK-CC2640R2-SDK_3.10.00.15

Currently i am working on ble cc2640r2f launchpad.

Below i have attached my code that receive data ,store data and send/.write same data to uart.

But facing issue when write or read data to/from external flash, the data getting duplicate or over written on other data when writing on uart.  

In this multi role project i will receive the sensor data from 2 or more BLE module periodically in simplegattprofile.c file then will store/write data in external flash and the read it and then written on uart. 

But in below code duplication and loss is found.

So please help me out to solve this issue or provide your valuable suggestion.

Here my code and the function that i am using....
