Other Parts Discussed in Thread: CC2650, CC2640
Hi
I'm still tring to acheave 1Mbps(2Mbps) data rate using CC2650 under proprietary mode but it's always failed.
Till now, I searched about this issues in TI E2E community but I never seen that 1Mbps test is ok in proprietary mode.
From my test result, in proprietary mode, maximum data rate is around 750Kbps under 4-FSK for cc2650. (500Kbps for CC2640).
I used rxPacketError code and configured rateword, prescale values correspond to 1Mbps (or 2Mbps)
if I apply 1Mbps configuration, Tx configuration is ok but receiver could not dectect any packet in proprietary mode.
My test result is below.
| symbol Rate( bps) | rateWord | sys clock | prescale | 2^20 | test result |
| 2000000 | 1048576 | 24000000 | 12 | 1048576 | RX Fail |
| 1000000 | 524288 | 24000000 | 12 | 1048576 | RX Fail |
| 500000 | 262144 | 24000000 | 12 | 1048576 | OK |
| 200000 | 131072 | 24000000 | 15 | 1048576 | OK |
| 50000 | 32768 | 24000000 | 15 | 1048576 | OK |
| 937500 | 491520 | 24000000 | 12 | 1048576 | RX Fail |
| 750000 | 491520 | 24000000 | 15 | 1048576 | OK for 4-FSK |
| 1000000 | 262144 | 24000000 | 6 | 1048576 | RX Fail |
| 1000000 | 655360 | 24000000 | 15 | 1048576 | RX Fail |
| 250000 | 163840 | 24000000 | 15 | 1048576 | OK |
Is it impossbile to reach 1Mbps higher data(include 2Mbps) in proprietary mode for CC2650 (CC2640) ?
If you have any solution, please dot not heistate to let me know.
Thanks Andy
