Part Number:CC2650EM-7ID-RD
Hello, I'm User who using SimpleLink CC2650 Development Kit.
i'm trying to communicate between two board with Bluetooth. i have set up 2 board(one is Tx mode, another is Rx mode).
and in Rx side, i'm trying to check the packet value via workspace console window.
but when i'm check the value, the values is always like below.

From the Tx side code, 0-1 index will be contain Sequence number and then other parts must contain random values. but it isn't.
what am i missing?
