Other Parts Discussed in Thread: CC1312R, , CC1190
We are using the CC1310 and CC1312R for our products currently. We will be making a new product which adds the CC1190 amplifier. We can use either the CC1310 or the CC1312R for the new product.
We are using WOR and use CMD_PROP_RX_SNIFF command with the mode is set to CarrierSenseMode_RSSIandPQT so the csConf.bEnaCorr will be set to 1. We are hoping that the RF processor can directly control the CC1190 to turn off the external RX amplifier as soon as possible in the sniff mode to conserver energy.
I see that there is a way to control the CC1190 from the RF processor in the CC1310/CC1312R so it is my hope that the RF processor will control the pins to best save energy in WOR mode.
From: https://dev.ti.com/tirex/explore/content/simplelink_cc13x0_sdk_4_20_01_03/docs/proprietary-rf/proprietary-rf-users-guide/rf-core/signal-routing.html, I see this note when using the CC1310, but no mention of the CC1312R:
The RAT_GPO1 signal is not supported in these scenarios:
- when using the sniff command (
CMD_PROP_RX_SNIFForCMD_PROP_RX_ADV_SNIFF) with preamble correlation enabled (csConf.bEnaCorr = 1)
Here are my questions:
1. Will the RF core be able to control the CC1190 to shut off the receiver when no RF is detected or when the preamble or sync word is not found (in WOR mode) so it will shut off very fast and certainly before the 100mS sniffing time we are using? If so, how do we set that up when using WOR?
2. Do I have to use the CC1312R to get what I want or can the CC1310 be used?
