BLE scan and advertising issues

I am trying to make a simple BLE scan and advertising program which is supposed to advertise a set of changing data and scan for other devices. The advertising is completely non-connective and works as a dumb beacon, and so is the scanning. The appli...

aci_gatt_add_char( ) returns BLE_STATUS_OUT_OF_MEMORY

Hello, I need to add characteristics without using the mechanism of the ioc configuration file. After only 3 (!) characteristics, the function aci_gatt_add_char( ) returns BLE_STATUS_OUT_OF_MEMORY.The available documentation is not usable to find a s...

It seems to enroll well to APP but when I try to send a message the aci_gap_init return the status value 0x46, BLE_STATUS_NOT_ALLOWED/* USER CODE BEGIN FD_WRAP_FUNCTIONS */tBleStatus P2PS_STM_App_Update_Buffer(uint16_t UUID, uint8_t *pPayload, uint8_...

STM32WLE and LoRa: Best way to detect Gateway down and make a new join

Hi, We have encountered the following situation: Once the equipment is Joined to the network, if by chance there is a power cut that affects the Gateway and it restarts, we have realized that we stop receiving data from the device. Our Device can ...

Differences on MX_TIMx_INIT()

I've found a significant difference in the function MX_TIMx_init() function generated from STM32 development tool for two different platforms. The first (it work) is generated for NUCLEO-F413ZH the second (it doesn't work) is generated for NUCLEO-WL5...

Which BLE ACI command is for subscribtion to notifications?

I can read characteristic value in P-NUCLEO-WB55 based application with ACI_GATT_READ_USING_CHAR_UUID command. However, I do not find any command for subscribe for notification (AN5270 docs neither STM32CubeMonitor-RF ACI commands). How can I subscri...

STM32WB BLE DATA Transmission Losses

Hii guys,we are using the STM32WB50 controller in our project. Stream 23000 bytes continuously in a second(46bytes after every 2-millisecond interval) using Bluetooth low energy system provided by the STM32WB microcontroller.To successfully transmit ...

Unable to change ATT MTU value on STM32WB55

I play with two STM32WB55 eval boards and BLE_CableReplacement project.It seems that whatever I try, I'm not able to change ATT MTU value to get more data troughput. It is set to 156 in the original project but it seems to stay at the default value 2...

how to receive notification data at STM32WB p2p Router from STM32WB BLE p2p Server?

I am able transmit 240 bytes of data from STM32WB BLE p2p server. This data want to receive on STM32WB BLE p2p router code.I am getting ACI_GATT_NOTIFICATION_VSEVT_CODE case executed but I see pr->Attribute_Value_Length is 20. I am transmitting 240 b...

STM32WB FW Update 1.12.1 Issue

Your updates are always valuable to me, but I've always suspected that update firmware won't bother a device already running.The same happened in the STM32WB new update (FW version 1.12.1), in this update BLE and GPIO interrupts are not working simul...
