LAUNCHXL-CC1310: How to configure the rate to 1.5 Mbps 4 GFSK in smart RF?

Part Number: LAUNCHXL-CC1310
Other Parts Discussed in Thread: CC1310

Hi team：

The 4FSK was designed for testing on both evaluation boards and no location was found for setting 4FSK. Can smart RF be set?

Also, in the default 2GFSK rate, the transmit and receive works fine at 600K rate, and at 700K rate, packet loss starts, but RSSI only -43 dBm, so why do you get packet loss?



Best regards

Alex

    SmartRF Studio only support prop for CC1310, 1.5 Mbps requires HSM. CC1310 does not have the required internal clock speed (MIPS) to handle more than about 600 kbps. 

    It's a number of E2E posts on 1.5 Mbps and CC1310.

    Hi Alex,

    EDIT: please refer to Siri's reply below as it is more comprehensive. Apologies for any initial confusion.

    1.5 Mbps requires a patch, with the rfPacketErrorRate example in the SDK providing documentation of the settings. Therefore, it is not supported in SmartRF Studio (as TheGhostOf points out).

    Regards,

    Zack

    It is correct that 1.5 mbps requires a patch (ghs = general high speed), and this patch is available in the SKD (rf_patch_cpe_ghs, rf_patch_mce_ghs, rf_patch_rfe_ghs)

    However, it does not require the use of the HSP API (high speed mode) but can use the normal prop API.

    The settings in the rfPacketErrorRate example (and the HSM API) is for the 4 Mbps High speed mode, and NOT for the 1.5 Mbps General High speed.

    The 1.5 Mbps ghs settings are not fully characterized and hence not in SmartRF Studio or in any of our examples, but you can find some settings here:
