Hi Yurii Glotov,

The TX power may not linear, but can not reproduce your issue.

Could you have a try on the BGTool + NCP empty target?

Hi Yurii Glotov,

You may missed the init part.

  /* Initialize stack */
  gecko_init(pconfig);
  /* Initialize Periodic advertisement */
  gecko_init_periodic_advertising();

Refer to https://docs.silabs.com/bluetooth/latest/code-examples/stack-features/adv-and-scanning/periodic-adv-example

Hi Neil Ross,

Not familiar with EnOcean PTM215B, but seems it send out BLE advertising only.

But our demo should use a connection style between EFR32 WSTK and Wireless Gecko iOS app.

You need to customize the example for receive advertising data and control the LED.

Hi Neil Ross,

Please follow bellow procedure, just not sure your radio board support this example or not.

Great!

The recommend way should be use .ld file to limited the FLASH and RAM size, remove some code like( "helpStr" in macros "RAILCMD_ENTRY (command, args, callback, helpStr)"), and reduce buffer size in flex-configuration.h. Refer to railtest_efr32_EFR32FG1V131F128GM32_20200708.sls.

What is the expected SIZE for your custom data?

Can 2KB fit it? If so you may use USEDATA it is not in main flash area.

Refer to example. 

In railtest_efr32_EFR32FG1V131F128GM32_20200708.sls I modify the ld file.

Glad to hear that you found the cause.

The target board should be custom board, right? Are you use internal DCDC? if not, please set it bypass or disable it.
