Hello everyone,
I'm currently using CCS 7.3.0
SDK: simplelink_cc13x0_sdk_1_30_00_06, simplelink_cc13x0_sdk_2_10_00_36
RTOS: tirtos_cc13xx_cc26xx_2_21_00_06, tirtos_simplelink_2_14_02_22
board used: CC1310DK_5XD_F128(custom RF module)
I have to combine GPIO for sensor interfacing and transmission(of RF signal at 865MHz) on one side (1st board) and reception(RF signal) and UART on another board.
I have tried code :

but it gives me error while linking
I also tried example of CC13xx TI-RTOS based RF TX/RX test platform using UART command interface: e2e.ti.com/.../469335
but it does not work in my case as it define for Launchpad.
If anybody has any suggestion/advice please suggest me, please reply as soon as possible.
thank you for the help in advance.
