Hello.
When will BGM 113 correspond to Mesh?
We want it very much.

Hi

In soc-thermometer example I have added health thermometer service to the GATT configurator. Do i need to add any extra code in main.c for any external app to be able to read the temperature value.

Thanks

By any chance is there a comprehensive explanation somewhere of what all of the different parameters are in the .isc file used in BLE and mesh projects?

Good afternoon, i have a quick question.  I've scoured both the WT32i datasheet and the iWRAP manual and i cant find any indication of the MCLK rates that are acceptable input into the WT32i when configured as a I2S slave.  I'm sure 44.1KHz, but can i use arbitrarily different rates, like 40KHz?

I am trying to build the BLE Android Demo Application using Android Studio. I downloaded and unzipped both the Bluegiga-Android-App and the library dependency, "tree-view-list-android". However it is unable to perform the Gradle Sync and throwing multiple dependency errors.

I have attached the error log for Gradle Build build.gradle files for application Bluegiga and the library.

Hi Everyone,

I am using the android ble api to provision a mesh network. Right now I am following the link establishment procedure specified by the SIG where I send the device UUID to the peripheral by writing to the Mesh_Provisioning_In Characteristic. I am supposed to receive an acknowledgement notification from the Mesh_Provisioning_Out characteristic but onCharacteristicChanged is not firing. I have subscribed to notifications with the following code as specified by the android Developer Guide

provOutCharacteristic = service.getCharacteristic(provOutCharacteristicUuid);
if (provOutCharacteristic == null) {
    Log.d(TAG, "No MESH_PROVISIONING_OUT characteristic found..., aborting Provisioining");
    return;
}else {
    Log.d(TAG, "MESH_PROVISIONING_OUT characteristic found");
    BluetoothGattDescriptor descriptor = provOutCharacteristic.getDescriptor(
            ProvoltGattAttributes.CLIENT_CHARACTERISTIC_CONFIGURATION.getUuid());
    boolean setVal = descriptor.setValue(BluetoothGattDescriptor.ENABLE_NOTIFICATION_VALUE); //returns true
    boolean test = gatt.writeDescriptor(descriptor); //returns true
    boolean subscribed = gatt.setCharacteristicNotification(provOutCharacteristic, true); //returns true
    if (subscribed && test && setVal) {
        Log.d(TAG, "Subscription to notifications successful");
    } else{
        Log.d(TAG, "failed to subscribe to MESH_PROVISIONING_OUT notifications");
    }
}

and all of the booleans return true. Additionally, the onDescriptorWrite method is called as well. Within the OnDescriptorWrite I call a method establishLink() that writes the device UUID to the Mesh_Provisioning_In characteristic. I was able to confirm that the characteristic is being written correctly because onCharacteristicWrite is called. Unfortunately onCharacteristicChanged is never called and I am unable to receive the notification that the mighty gecko chip is supposed to return when I send it the link open packet (which contains the device UUID). What do I have to do to receive this notification.

Note: I have commented out onCharacteristicWrite to prevent that callback from interfering with onCharacteristicChanged being called but the method still does not fire.

Can we use SI4432 to create a mesh network?

 

If yes then anyone please guide me to go in that direction, because i'm new in this field so small help can be helpful for me from anyone,

Thanks regards,

Hi,

If I run the SOC empty example built with SDK 2.4.2, it works fine and I can start the firmware on both the WSTK and my own board. I've just added the PF7 LED on after start to see it happen (both WSTK and my board have a led on PF7).

If I run the same example built with SDK 2.8.1, it works fine on WSTK but it doesn't boot on my own board. Sadly I have no debug connector on this board, so it's very hard to debug.

I've search a lot on the forum and found that the bootloader has changed. On this page : https://www.silabs.com/community/wireless/bluetooth/knowledge-base.entry.html/2017/04/12/adding_gecko_bootloa-osqt, it written :

• no bootloader is included in any Software Exmaple projects

But later : 

Fourth method (If you have SDK v2.7 or later)

1. Flash a demo to your device
   • flash the SoC - Empty demo to your device first. This will flash SoC - Empty application with Bluetooth in-place OTA DFU type Gecko Bootloader

 

Does the SOC empty example contains the bootloader or not ?

In case it doesn't, I've tried to add the bootloader with the first method, but it still doesn't work. Which procedure should I use ?

Thanks for your help.

Hi,

I want to trsmite value of one characteristic from ble113 to bled112 using BGScript. As a basic I use this article, but cant understand how to implement function like a attclient_read_by_handle, attclient_attribute_write, etc.

(I think it's necessary to use them, maybe I'm wrong) 

Maybe in KB already exist examples or articles with appropriate GATT structure and BGScript for both devices in my problem.

I will be grateful for all links in the right direction.

Sorry for duplicating my previous post, I did not receive an answer, and my problem should be solved as soon as possible.

 

Hello,

I'm doing a project using the BGM111 module. I have accelerometer datas that are read by an external MCU (LPC1227) and I wanna transmit these datas to the BGM111 in order to transmit the datas to a PC and be able to visualize the datas from the accelerometer on a graph.

My question is what should I do to transmit the data from the MCU to the BGM111 and how can I do it ? Also what should I do to transmit the data from the BGM111 to a PC ? It's the first time i'm using the BGM111 module so I really don't know how to use it. I don't know if I can type my code using only the MCU (LPC1227) IDE or I have to use another IDE, if I have to type the code in C or in BGScript, I really don't know what to do and how to start.

As I said I just wanna send datas from my external MCU to the BGM111 using UART interface and then send these data from the BGM111 mdoule to a PC. It's really really urgent because it's a for a my graduation project, I really need your help!!!

Thank you in advance.

Hi everyone, 

I'm working with a blue gecko starterkit. i'm following this example https://www.silabs.com/community/wireless/bluetooth/knowledge-base.topic.20.10.html/spp-over-ble_c_examp-mnoe, but i can't make it work with another ble device.

Using light blue on iPhone i discovered all UUIDs, but i still can't get how to interrogate properly the device.

I want to connect BGM121 to one of the device's services, made of two characteristics (chr1: WriteNoResponse, chr2: Notify): writing a command on chr1 i should be able to get data from chr2.

 

Can you help me? i don't know where to start.

 

Thanks in advance

Hi,

If we program and run firmware application in a "EFR32BG13 chip" by using the debugger all is ok. (The pcb is our own.) Studio V4, MCU SDK is 5.4.0.0

After a hard reset or power up it does not run/start the code (while connected to the starter kit or not). Works as soon as we load/start by debugger. 

(In addition we can not erase the chip in the simplicity commander, we get "Unable to halt target". Else debugging/ app-reload works nice.)

"Bootloader combined" and application programs fine and runs if no hard reset is done by button. It all works/resets if BGM111 is used instead of EFR32BG13.

Any thoughts?

Best regards,

Hi,

Anyone have capacitive sense example project for EFR32MG12P?. The project should use caplesense library, because I need this to use with bluetooth sdk project. What I need is a touch interrupt when the mcu is in EM2. Then it should process touching and do something if specific button is pressed. Please help.

Thank you.
