CC2340R5: cc2340R5 coexistence

Ryan,

I enable coex in sysconfig.

https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/538/6835.basic_5F00_ble.syscfg

I also add  "RCL_GPIO_enable();" in code.

int main()
{
/* Register Application callback to trap asserts raised in the Stack */
halAssertCback = AssertHandler;
RegisterAssertCback(AssertHandler);

Board_init();
RCL_GPIO_enable();

No matter, I set GRANT to high or low. I can still find basic_ble device.

I measure request and priority pin. They are always low.

I miss something?

What in your view is RCL_GPIO_enable used for?  You shouldn't have to add any APIs to the project.  GRANT is an input to the CC2340R5, not an output like REQUEST and PRIORITY, as described in this Coexistence Guide.  What Coex mode are you using?  Perhaps you would get some use out of RF Output Debugging as well.

Regards,
Ryan

Ryan,

I force Grant low\ high to check if coexistence works or not. 

I also enable LNA_EN and PA_EN. LNA_EN and PA_EN always has signal no matter GRANT is high or low.

no matter I add "RCL_GPIO_enable();" or not, the result is the same.

Any idea?

Thanks for the information Frank, I am having a BLE expert test and they will report to you shortly.

And I do apologize as I've recently found an internal page which insinuates that BLE Coexistence will not be available until SimpleLink F3 SDK v9.20, so the existing Coexistence option may only be intended for IEEE 802.15.4-based solutions (such as Zigbee).

Ryan

Ryan,

Can I know when v9.20 will be released?
