[pallavi]

hello, i am implimenting ir with nrf24le1 but after adding the transmit.h,transmit.c nordiac_common.h and lib_ir_common.h the code is compiled successfully but it shows this linking warning.i am not getting exactly what i have to add so that i can remove this warning( *** WARNING L1: UNRESOLVED EXTERNAL SYMBOL. SYMBOL: LIB_IR_TRANSMIT_DATA_SENT_CALLBACK).if anyone has implimented this then give me a solution for this problem.

Hi pallavi,

Could you point me to the place you get the infrared library from ?
