Hi Gary Sugar,

19.5dBm need a 3.3V voltage.

Please check below config.

1. #define HAL_PA_VOLTAGE                                (3300)
2. .pa.input = GECKO_RADIO_PA_INPUT_VBAT,

Also note that some part is limited at 10 dBm.

Best Regards,

Eric Su

Have you checked the BRD4162A_EM3EM4.zip?

The HFXO is disabled automatically when entering EM2, EM3, or EM4. 

Which clock are you intend to shutdown?

I changed to version 2.6.4 and now it works. You have a major bug in the examples of V2.6.0.0.

Please be aware of this and notify users of the problem, and investigate when it is brought to your attention.

Note if 900 and 2.4Ghz RAIL work and connect does not , you have a problem, please don't assume the user is at fault and check the version specified and not the one you know works.

Thanks.

Glad that finally you make it work.

Thanks for report the bug.

Sorry, but I can not check on V2.6.0.0 any more, because after upgrade to V2.6.4.0, we can not back to V2.6.0.0.

RAIL is Radio Abstraction Interface Layer, it is a library.

Connect is a stack, up to the Network layer.

For more information on RAIL and Connect, refer to 1. What is RAIL & Connect

Read UG305 for understand DMP.

DMP(dynamic multiprotocol), that is 2 protocol run on one board, usually it is (BLE + Zigbee), (BLE + RAIL), (BLE + Connect). Do you have use case like this?  (BLE + Zigbee) needs IAR. (BLE + RAIL) and (BLE + Connect) can use GCC. If you don't use DMP, you can use GCC.

Not sure about thread DMP.

Our WSTK integrate a SEGGER J-link interface, if you buy both communication modules and the programmer card separately, it works.

Can you be more specific on works but only after...consumption?

I tested on WSTK(BRD4304A), it works well.

Do you have a WSTK to check it directly.

To solved the problem,  we should first locate the problem.

Are you use a custom board?  What is the schematic?

I'm not sure if I2C cause it, can you check this by a HW cut/remove?
