Hi

What is the difference in functionality of VMCU_IN and 3v3 pins in radio board 4306A?

I was connecting just the radio board to external voltage supply. I hooked up 3.3V external supply to 3v3 pin on radio board ,GND connected to ground , TX to RX and RX to TX. 

But this connection setup is not able to communicate with the PC bluetooth.

But it starts communicating if I put 3.3V external supply to VMCU_IN pin ,GND connected to ground , TX to RX and RX to TX. 

 

Can you help me clarify if I am missing something?

Thanks

Hi,

We tested the BGM13P module using the SLEXP8027A dev kit, and have now included the module on a custom board.

We expected the module to come pre-programmed as it is on the development board but it appears not. On boot we get a few bytes received on an odd baud rate (~117Kbps) and that's it.

 

What are the steps necessary to flash the modules on our custom board with a similar firmware as in the SLEXP8027A? Can this be done using UART only or does it requires the use of the SWD debug connector (which fortunately we have populated just in case)? If so, which tool to use?

 

Thanks,

Theo

How long does the flash_ps_defrag() procedure take to run? Is there a figure for the number of times the flash can be defragged?

Thanks, SimonM

Hello 

 

I made android app by  MIT APP INVENTOR 2 

I am using self-provisioning.

 

when i use below for PROXY ENABLE, it can connect well.

        gecko_cmd_le_gap_set_advertise_report_scan_request(0,false);
        gecko_cmd_le_gap_set_advertise_phy(0, 1, 1);
        gecko_cmd_le_gap_set_advertise_configuration(0,1); /* use legacy PDUs, non-anonymous advertising, resolvable address*/
        gecko_cmd_le_gap_set_advertise_timing(0,160,160,0,0); /* 100 ms interval, continue until stopped*/
        gecko_cmd_le_gap_set_advertise_channel_map(0,7); /*all primary advertising channels*/
        gecko_cmd_le_gap_start_advertising(0, le_gap_general_discoverable, le_gap_connectable_scannable);

 

But 

When i use below, it never connect with app. But nordic" nrf connect "can connect.  silicon lap "blue gecko" do not connect with proxy device.

            result = gecko_cmd_mesh_test_set_local_config(mesh_node_gatt_proxy, 0, 1, "\x01")->result;
             //gecko_cmd_le_gap_set_advertise_timing(0,160,200,0,0); /* 100 ms interval, continue until stopped*/

             if(result)
             {
              printf("set proxy failed with code 0x%x\r\n", result);
             }

 

I added android apk.

Why do not connect ?

 

Thank you.

I am testing the OTA feature on BLE mesh. it is working fine when it is not provision and sending unprov_beaconing. However, after provision, it seems to stop advertising the OTA advertisement. therefore, it cannot proceed to OTA upgrade. Could you advise how to enable it for OTA upgrade after light/switch provisioned.

Thanks,

Jerry

Hello,

How is the Unprovisioned Device Beacon's Device UUID generated (BLE Mesh)?

Can this Device UUID be changed?

 

Thanks,

Hello,

We have integrated a BT121 chip into our own board, and would like to use the BGTool to interact with it, for testing purposes.

Connection between the test PC and the integrated chip is through direct tunnel, using a serial RS232 cable. 

The image that is loaded on the chip is the following example (which, to our understanding, is supposed to be compatible with the BGTool): example\bt121\BT121_BGAPI_UART115k.bin

Currently, we have not been able to establish a successful connection between the BGTool and the BT121 through its com port (attempts result in a "device is not responding" error).

I'm convinced that it is the port settings that are preventing this from happening - we don't see any data throughput when attempting to connect or send commands through the direct tunnel, using the BGTool. One thing of note, is that upon disconnecting, the BT121 module spits out a hexstring of 0x00; there is no activity from the module otherwise. 

Are there specific settings for parity, databits, stopbits, handshaking and breaks, that the BGTool expects?

Let me know if any other information is required. Thanks for your attention to this.

Hello, everyone!

 

I'm using EFR32BG13 plug-in MCU to build an embedded gateway device that can now bind, publish and subscribe to node messages, and switch nodes to control light nodes.However, now there is a problem. After the gateway completes the publication and subscription of the node for the first time, the switch node has no problem in controlling the light node. When the light node and the switch node are cut off and restart at the same time, although the light node will print Debug message: evt gecko_evt_mesh_friend_friendship_established, the switch node will print:Friendship established, when actually the switch node sends the control message again, the optical node does not perform the response action and no Debug message is printed.

 

A) optical node routine comes from SDK without any modification.

 

B) the switch node routine is derived from SDK and modified to (0x3) gecko_cmd_mesh_node_start_unprov_beaconing(0x2);PS: I don't know if the modification here causes the failure.

 

C) embedded gateway equipment for KBA "KBA_BT_0501: BT Mesh embedded provisioner example", most of them are reference sample port, the only modification is that I omitted the GATT supply request mode and relevant events, and used pb-avd supply mode for all nodes.

 

 

 

The attachment is the Debug message printed by the device.

Hello 

I can not find an explanation for BT Mesh Memory Configuration.

Guidelines for optimization are required.

Does anyone know the documentation related to this?

Thank you.

 

Hello,

based on SOC thermometer RTOS example, I am looking how to define and use RTOS interrupts.
Just need simple RTOS interrupt reacting to button (GPIO) that will post message into queue (OSQPost).

QUESTION: how to define and use RTOS GPIO interrupt for rising edge (PF4 pin)?


Till now I have used general GPIO interrupt, that works but ends randomly with RTOS error in OSQPost function:
interrupt setting (initialized in main.c)
 

// Configure PF4 as input with glitch filter enabled
GPIO_PinModeSet(BUTT_PORT, BUTT_PIN, gpioModeInput, 1);//gpioModeInputPullFilter

// Enable IRQ for even numbered GPIO pins
NVIC_EnableIRQ(GPIO_EVEN_IRQn);
// Enable rising-edge interrupts
GPIO_IntConfig(BUTT_PORT, BUTT_PIN, 0, 1, true);
//clear interrupt flags
GPIO_IntClear(0x5555);

 

ISR routine:
void GPIO_EVEN_IRQHandler(void)

{

RTOS_ERR  err;

uint32_t message;
message = 1; // send system message to initiate POPP sequence

       OSQPost    ((OS_Q      *)&AppQ,

                   (void      *)message,

                   (OS_MSG_SIZE)1,

                   (OS_OPT     )OS_OPT_POST_NO_SCHED ,
                   (RTOS_ERR    *)&err);

       //Check error code.

       //APP_RTOS_ASSERT_DBG((RTOS_ERR_CODE_GET(err) == RTOS_ERR_NONE), 1);

    if (err.Code != RTOS_ERR_NONE)

    {

       printf("OSQPost \tErr: %d\r\n", RTOS_ERR_CODE_GET(err));

        /* Handle error on message queue create. */

GPIO_IntClear(0x5555);

    }
 

***********************************************************************************

************** Micrium RTOS Interrupt ************************************************

***********************************************************************************

 

I have following Micrium documentation and rewrite ISR:

 

Left previous interrupt definition:

// Configure PF4 as input with glitch filter enabled
GPIO_PinModeSet(BUTT_PORT, BUTT_PIN, gpioModeInput, 1);//gpioModeInputPullFilter

// Enable IRQ for even numbered GPIO pins
NVIC_EnableIRQ(GPIO_EVEN_IRQn);
// Enable rising-edge interrupts
GPIO_IntConfig(BUTT_PORT, BUTT_PIN, 0, 1, true);
//clear interrupt flags
GPIO_IntClear(0x5555);

 

void GPIO_EVEN_IRQHandler(void)

{

RTOS_ERR  err;

uint32_t message;

 

CPU_SR_ALLOC(); // Save the CPU registers

       CPU_CRITICAL_ENTER(); // Protect a critical section

       OSIntEnter();

CPU_CRITICAL_EXIT();

message = 1; // send system message to initiate POPP sequence

       OSQPost    ((OS_Q      *)&AppQ,

                   (void      *)message,

                   (OS_MSG_SIZE)1,

                   (OS_OPT     )OS_OPT_POST_NO_SCHED ,
                   (RTOS_ERR    *)&err);

       //Check error code.

       //APP_RTOS_ASSERT_DBG((RTOS_ERR_CODE_GET(err) == RTOS_ERR_NONE), 1);

    if (err.Code != RTOS_ERR_NONE)

    {

       printf("OSQPost \tErr: %d\r\n", RTOS_ERR_CODE_GET(err));

        /* Handle error on message queue create. */

OSIntExit();     

    }

 

For some reason ISR does not work properly executes after first rigger initiation and runs for ever, till adding GPIO_IntClear(0x5555) to the end of ISR;
looks I am doing something wrong but what? I was looking for Micrium RTOS interrupt examples instructions but practically did not find any useful, maybe overseen?

 

Thanks a lot for help

Hello

following "https://www.silabs.com/community/wireless/bluetooth/knowledge-base.entry.html/2016/12/12/bgm111_button_press-zsB1" 

it results in errors:
C:\workspace_01\Micrium_014\GNU ARM v7.2.1 - Default/../main.c:406: multiple definition of `GPIO_EVEN_IRQHandler'
C:\workspace_01\Micrium_014\platform\emlib\inc/em_gpio.h:802: multiple definition of `GPIO_ODD_IRQHandler'

once there is multiply definition ingpiointerrupt.c, from which gpio.h is called

Hello Forum,

We are designing a Bluetooth network for one of our clients with over 100 BGM111's as Central devices to collect information from sensors in field and relay the data to local server. All these 100 BGM111's will have to be powered from external 12V DC line and we are planning to use a 3.3V Buck Converter for each BGM111. We request help on the below,

1) The Buck Converter's output Voltage Ripple is 25mVp-p at 664kHz frequency. Is this ripple with-in BGM111's acceptable range or should we use an LDO to filter the ripple?

2) Can we have BGM111 and Buck Converter circuitry on the same pcb? Since we only have BGM111 on PCB, we have lot of free space which can house the Buck Converter circuitry also but not sure if that will impact BGM111's performance and range. Range is of utmost priority and space is not a constrain in our design. If required we can have them on seperate PCBs and connect through cables.

3) For a PCB with BGM111 only on board, what is the recommended number of layers? (2 or 4)

4) Does the thickness of GND plane Copper on either sides of BGM111 effect the range? If yes, what is the recommended thickness of Copper? (Datsheet specifies the length of GND plane on either sides of BGM111 should be 17mm for maximum range. We would like to check the thickness effect if applicable)

5) Does the thickness of PCB effect BGM111's range? If yes, what is the recommended thickness of PCB.

Thanks,
Ravi

Hi everybody,

I need to write some GATTDB data (for example, s/n characterictics, software version...) in production time.

Is there any way to get it without modifying ISC file in the project and recompiling all the solution again ? 

Thank you,

Asier.
