Hello, 

I read the AN1086 and this https://www.silabs.com/community/wireless/bluetooth/knowledge-base.entry.html/2018/05/30/using_blue_geckoapp-88g7 but I don't know were I'm wrong.

My target is flashed with bootloader-storage-internal-ble-combined.s37.

When I use the computer programme to update the application, it works only if I lunch the programme 2 times. The first time, the programme indicate:

BTW, my real problem is on the Android app but I find it strange that it works only the second time... (but it works)

On my phone I have the Silicon Labs App. I connect to my device, go to OTA Setup then select my app.gbl.
When I press partial OTA, I can see my device swithing to the bootloader (a LED stops blinking on my board)  and the checkbox "OTA BEGIN" is checked. Then a message "device disconneted" appears and nothing else happens (OTA upload stays at 0%).

I try with all priority level, with MTU as small as possible...

Where I'm wrong ? Are all these programs compatible together (Android app Vs Bootloader 1.6) ?

Thanks in advance for help !

HI,

I am using EFR32MG12P433F1024GL125 and bluetooth stack is 2.4.2. by using mobile app.I need to poll the GPIO pin After booting the Board.,Here my GPIO  pin act as a Button,

hi there,

     i working in BGM11s  , while studing the  Ug136  in page number 14 a note describes that only 38 Mhz crystal frequency is only support to the bluetooth since it is set as default, but while reading the schematic diagram of BGM 11s radio board BRD4303 the external oscillator pin is shorted with each other , without the crystal how the program works in BGM11s   (BRD4303).

Can i change the setting to HFRC oscillator with  lower frequency for energy optimization instead of crytsal oscillator .

Hi,

Going through PWM configuration, finally get into PWM by help of peripheral examples, I have 2 x independent synchronous PWM 16bit outputs right now connected to LEDs. It seems to be working, till l initialize BLE stack, than these PWM LEDs start flashing periodically. Aplications comes from “SOC - thermometer”

I have used TIMER0, CH0 and 1. Looks BLE stack is using these resources.

Here is the questions:

Which TIMER resources BLE stack (Gecko SDK Suite v2.4.1: Bluetooth 2.10.1.0, Flex 2.4.1.0, MCU 5.6.1.0, Micrium OS Kernel) is using?

Thanks

HI，

早上好！

我现在用EFR32开发NCP模式，现在需要通过发送Command来连接控制一盏MESH Light，但是我不太懂Command之间步骤过程，能请说明下或提供些参考吗？

 

TKS！

hi

我使用ncp模式开发，在外挂MCU的库中需要包含以下路径文件夹中所有文件吗？

•c:\SiliconLabs\SimplicityStudio\v4\developer\sdks\gecko_sdk_suite\<version>\app\bluetooth\examples_ncp_host\empty\

•c:\SiliconLabs\SimplicityStudio\v4\developer\sdks\gecko_sdk_suite\<version>\app\bluetooth\examples_ncp_host\common\

•c:\SiliconLabs\SimplicityStudio\v4\developer\sdks\gecko_sdk_suite\<version>\protocol\bluetooth\ble_stack\inc\host\

• c:\SiliconLabs\SimplicityStudio\v4\developer\sdks\gecko_sdk_suite\<version>\protocol\bluetooth\ble_stack\inc\common\

• c:\SiliconLabs\SimplicityStudio\v4\developer\sdks\gecko_sdk_suite\<version>\protocol\bluetooth\ble_stack\src\host\

Hi,

I have to design a specific antenna for this Bluetooth MCU : EFR32MG13P632F512GM48

On datasheet, I don't find the RF impedance on pin 2G4RF_IOP. What is the value ?

Best regards

Silicon has repackaged BLE MESH, making me even more confused.Or should there be some documentation that can be explained in detail?

1. What does MESH_REQUEST_FLAG_RESPONSE_REQUIRED == 1 mean?
     What does MESH_REQUEST_FLAG_RESPONSE_REQUIRED == 0 mean?
     I want to know their relationship with GET/SET/SET UNACK.

2. What effect will the next update or response have? ?

  mesh_lib_generic_server_register_handler(MESH_GENERIC_POWER_ON_OFF_SETUP_SERVER_MODEL_ID,
                                           0,
                                           power_onoff_request,
                                           power_onoff_change);

 

  if (request_flags & MESH_REQUEST_FLAG_RESPONSE_REQUIRED) {
    power_onoff_response(element_index, client_addr, appkey_index);
  } else {
    power_onoff_update(element_index);
  }

why "response" is MESH_GENERIC_POWER_ON_OFF_SETUP_SERVER_MODEL_ID

, but the “update” is MESH_GENERIC_POWER_ON_OFF_SERVER_MODEL_ID?

I really want to work on my own, but I find it difficult to move, and I can only ask questions constantly.

Thanks.

Hello Forum,

Does anyone know how to disable DCDC Buck Converter in BGM111?
The latest version of Bluetooth API manual says 'cmd_hardware_enable_dcdc' is deprecated and no new command suggestion is available.

(REASON TO DISABLE DCDC CONVERTER : The electrical noise in our PCB board is effecting sensor measurements. Not sure about the source, we would like to disable BGM111's DCDC Buck Converter and check)

 

Thanks,

Ravi

Hi,

I am trying to find the RSSI of a nearest mesh member, using the following code:

case gecko_evt_le_gap_scan_response_id:
			printf("evt:gecko_evt_le_gap_scan_response_id\r\n");

			//
			struct gecko_msg_le_gap_scan_response_evt_t *scan_resp;
			scan_resp = (struct gecko_msg_le_gap_scan_response_evt_t *)&(evt->data);

			printf("\tRSSI %d, Type %d, Addr 0x%02X%02X%02X%02X%02X%02X, Addr Type %X, Bond %d, msg len: %x, msg: 0x", scan_resp->rssi, scan_resp->packet_type, scan_resp->address.addr[0], scan_resp->address.addr[1], scan_resp->address.addr[2], scan_resp->address.addr[3], scan_resp->address.addr[4], scan_resp->address.addr[5], scan_resp->address_type, scan_resp->bonding, scan_resp->data.len);

			for (uint8_t i = 0; i < scan_resp->data.len; i++)
				printf("%02X", scan_resp->data.data[i]);
			printf("\r\n");

			break;

 

& the setup code as

 

gecko_cmd_mesh_node_set_adv_event_filter(0x000F, 0, NULL);

 

This all works, and reads RSSI of the scanned nodes.

But I need some way of filtering these scanned nodes to the mesh the current device is part of. Can I filter by netkey or appkey etc?

 

I am trying to not have to pass a list of BLE addresses around the network.

Cheers for your help!

Hello, I have a short question:

in chapter 8 (page 52) of the datasheet of the BGM13P the pin definitions are shown.

Does someone know if it refers to BOTTOM or TOP view?

Thanks a lot,

Christoph
