STM32 MCUs Wireless

When we can expect the Segger to support stm32wb?https://www.segger.com/downloads/supported-devices.php

In every example which i have tested after second device disconnection it stops Advertising. After a short investigation i found that aci_gap_set_discoverable waits for hci_cmd_resp_release. I don't know if problem is with stack on CM0 or it is problem in STM32Cube_FW_WB_V1.0.0I need answer ASAP: i have to decide if this Product will be used in our new (quite big) project.Best RegardsWojtek

I am running the Mac_802_15_4 FFD and RFD examples on 2 STM32WB55 Nucleo bords.On Coordinator, the APP_MAC_mcpsDataIndCb function is triggered but don't save the data in the Mac_dataInd_t structure. What can I do to receive data?

Hey everyone,I'm using a stm32wb55 nucleo board.When i'm using ST example about RTC, i have a problem with the accuracy of RTC and i want to know how i can configure RTC for increase her accurancy? I.E.: all of 10 minutes i lose 6 secondsThanks in advance for any help.

Hello, everyone. I'm a beginner in Lora. And I need to program an I-NUCLEO-LRWAN1 extension card on a STM32L073 Nucleao-64 to send se

With Cortex M0+ (BLE) running, how Cortex M4 writes data on flash ?The reference manual says during flash writes all acess are denied.

Hi! I would like to build a wireless mesh system for a parking lot. Specifically, I have one border Router (Raspberry with STM23WB Nucleo) and several end devices (STM32WB Nucleo / Battery + Solar) that are located under each car. That means, that the end devices have to pass the message to its neigbors. Will this work? I am currently thinking about the Example Application "Multiboard" from the STMCubeWB SDK as a template.

Hi, guys.Just downloaded the altium designer design file of P-NUCLEO-WB55.https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/stm32-nucleo-expansion-boards/p-nucleo-wb55.html?icmp=tt10667_gl_lnkon_feb2019While I was enjoying the layout, I found that there are many pads, instead of vias, connecting tracks or layers.I know that they are physically the same, just curious why use pads instead of vias? I suppose pads are used to connect PCB and footprint, no?below is an example, captured from the design file.

Hello,Once i create a project with CubeMX for B-L072Z-LRWAN1 kit, how i can add I-CUBE-LRWAN libraries externally. Before this project i used ping-pong example in called library. It was divergent for which i want to do. Thanks.

Hello,I am teacher in France and newbe for CubeMX and TrueStudio. if want to integrate the soft en.cube_LRWAN1 in the a Nucleo-L476RG with i-nucleo_LRWAN1. I compile a project with the Nucleo-L476RG start for cubeMx with a solution en.cube_LRWAN1 and in the main the program stop with the instruction: LORA_Init( &LoRaMainCallbacks, &LoRaParamInit);.exists a technique to integrate easily en.i-nucleo_LRWAN1 in a project with a nucle-l476rg?Best RegardMichel Arnaud

I used STM32Cube to generate a project for TrueStudio on the STM32WB.My target is the STM32WB55 Nucleo.But the project will not compile. Other posts say check the project target settings. There is no selection for STM32WB.Do I need to add another support package?If so, how do I do that?

Hello,I choose in board selector to B-L072Z-LRWAN1 kit and create a project. But i cannot reach radio modules in TrueStudio, but only hal files. Should i add files myself, if so which files. Thanks.

I am currently trying to establish a simply communcation between two B-L072Z-LRWAN boards. For starters I wanted to set up the SPI interface on the STM32 to communicate with the SX1276. I generated code using cube MX by selecting the used board and writing GPIOs seems to be working. However i can not get the SPI to communicate. I tried reading the RegVersion to verify the communcation but all I get back is 0x0. The code for reading the register is listed below. uint8_t addr = 0x42 & 0x7F;//0b01000010; uint8_t tx_dummy; uint8_t rx_data;   //sending address HAL_GPIO_WritePin( RADIO_NSS_GPIO_Port, RADIO_NSS_Pin, 0 ); HAL_SPI_TransmitReceive( &hspi1, ( uint8_t * ) &addr, ( uint8_t* ) &rx_data, 1, HAL_MAX_DELAY); HAL_GPIO_WritePin( RADIO_NSS_GPIO_Port, RADIO_NSS_Pin, 1 );   //receiving data HAL_GPIO_WritePin( RADIO_NSS_GPIO_Port, RADIO_NSS_Pin, 0 ); HAL_SPI_TransmitReceive( &hspi1, ( uint8_t * ) &tx_dummy, ( uint8_t* ) &rx_data, 1, HAL

We use B-L072Z-LRWAN1 (Murata TypeABZ) dev board, where we were able to set-up clock sources to use HSI (@32MHz with PLL - HW_SetHSEasSysClock(void)) instead of HSE during Sigfox transmission. From the firmware perspective, everything is fine, but we were unable to receive data (Sigfox infrastructure), while the same HW with HSE is OK.As the sigfox stack is closed, we don't know if we can do more...What is the reason behind HSE usage? Is it the hard-requirement, or not? Is it possible to set-up HSI somehow?

Dear,I’m working with a B-L072Z-LRWAN1 Discovery Board and AT_Slave sample code of CubeExpansion_LRWAN_V1.2.0.I being able to JOIN to a Gateway, but when I try to send a frame to the Gateway with command AT+SEND= ...   , the most of trials I get an AT_ERROR even if the equipment is joined.Also I tried to send each 5 second the command AT+SEND … and for my surprise, only one of these commands is accepted with “OK�? (and received as well on Gateway) approximate each 150 seconds Does anybody why?Also I tried to deactivate the Duty cycle restriction with AT+DCS=1 with identical result.The complete sequence is:AT<CR><LF><CR><LF>OK<CR><LF>AT+JOIN<CR><LF><CR><LF>OK<CR><LF>JOINED<LF><CR>AT+NJS=?<CR><LF>1<CR>

After seeing the STM32WB55 series, i want to shift , but it don't have zigbee till now but they mentioned as coming soon? So, will they update it over the internet or using any software? Will it inter-operable with Digi Xbee s2c/Pro module?

Hello, i am working with this kits and library. Using ping-pong example for learn but now i want to add a new uart then read gps datas and monitor on a screen. CubeMX have B-L072Z-LRWAN1 in board section. But after generate code you have just a idle code. Is there a option import I-CUBE-LRWAN library to CubeMX and use new peripherals.Thanks.

Hello,I'm using a I-NUCLEO-LRWAN1 shield plugged on a NUCLEO L073RZ board. I'm trying to make the I-CUBE-LRWAN AT-master example run on the Nucleo L073rz. As documentation explain i opened SB13 and SB14 and closed SB62 and SB63, i also redirected the stlink to the uart4 with flying wire to be able to program the board.To connect to my LoRa server i need to change my DEUI but the shield return an error "ERROR_INVALID_ARGUMENTS" (which is not even in the documentation of the software package) when i try to change it with the AT+EUI=XXXXXXXXXXXXXXXXX command. Does anyone have any idea on why we can't change the DEUI?

Hi,I'm using STM32 Lora Discovery kit to run the code generated by cubemx for RTC, While on debug i'm get the RTC values but when run normally then i'm not getting any values except the initialised values for the time.Thanks & Regards,Vijay Rakesh

could you give me any hints what changes are needed to convert IP64Router example from 6LPETH1 (Nucleo-F429ZI + X_NUCLEO-IDS01A4) into an IPv6 router ?

Does anyone use STM32WB55 now? The Reference Manuals is not available on this website.Neither KEIL nor IAR seem to support the chip�?

Hi, I am modifying the sample program End_Node on the kit B-L072Z-LRWAN1.UART2 is configured as a virtual com and works correctly on PA2 and PA3 pins. I'm trying to add a second serial on PA9 and PA10 but I can not receive and transmit anything. I then tried to modify the working virtual com to use the PA9 and PA10 pins but without success.The initial working configuration is as follows:#define USARTx USART2 #define USARTx_CLK_ENABLE() __USART2_CLK_ENABLE(); #define USARTx_RX_GPIO_CLK_ENABLE() __GPIOA_CLK_ENABLE() #define USARTx_TX_GPIO_CLK_ENABLE() __GPIOA_CLK_ENABLE() #define DMAx_CLK_ENABLE() __HAL_RCC_DMA1_CLK_ENABLE()   #define USARTx_FORCE_RESET() __USART2_FORCE_RESET() #define USARTx_RELEASE_RESET() __USART2_RELEASE_RESET()     #define USARTx_TX_PIN GPIO_PIN_2 #define USARTx_TX_GPIO_PORT GPIOA #define USARTx_TX_AF GPIO_AF4_USART2 #define USARTx_RX_PIN GPIO_PIN_3 #define USARTx_RX_GPIO_PORT GPIOA #define USARTx_RX_AF GPIO_A

We are looking at sending around 1Mb/s of data with a latency of under 1ms.
