The following registers are configured:
0x107 buffercfg 0x01
0x3AA extpa_msc[7:4] 0xF
0x3C8 irq1_en1 0x08
All other registers keep default, so the data rate should be (256*78 + 32)*100 bps = 2M
And the packet mode is IEEE 802.15.4-2006.
But when i send 128bytes and using spectrum analyzer to find the duration of TX, it cost 5ms so the maximum data rate will be 200*128B = 204 kbps, only ten percent of the data sheet giving.
Anyone could help to explain or show your ideas to solve this issue? If you need other information about the driver, please also let me know, thanks.
