I want to use Basic mode with fix data length on CC2543.
I base on the CC254x PER example code and modify it to Basic Mode with fix data length to transmit data out (PRF_TASK_CONF.MODE =00).
In this mode, the packet format should no length field and fix the transmit data length. The time of transmit should be the same when I put different value on first byte into TXFIFO.
But in my measurement the transmission time is follow the first byte( length field). Measured the time of transmit using OBSSEL0 and RFC_OBS_CTRL0 = 0x09 (TX_active).Is it normal? Or configuration should be modified? My code attached as below.swrc251b_BasicMode.zip
