I want to send 2 kbyte data using BLE in WB55.Becasue the packet size is limited to 245 byte (it may be 509 byte if change ATT-MTU to 512 but still I couldn't make it.)So, I wonder whether there is good example for this.Could you suggest anything?
How can I check the ATT-MTU of the current connection (not setup)?What coding can I use to check? For example, I want to return ATT-MTU size through USART after measuring it in the microcontroller.
During several trial to use ACI_GATT_Write_Long_Char_Value,I found that the microcontroller dosen't start its BLE advertisement anymore.It only can indicate wireless firmware version.I think that some transmission cause an error.So, I tried to rewri...
HI everyone, I'm working on creating a sequence of files, that everytime the program starts to run, it creates a sequential file of the last one created. But I'm having troubles trying to create a logic that compares the name of the last file and cre...
Hi.I can see that CFGBSY bit is set and reset in some MX peripheral init functions, but the main problem is that it stays set after MX_TIM1_Init and it locks my flash for any operation.Did anybody saw this kind of problem?Any help will be appreciate...
Hi, I would like to use USART1 insted of LPUART1 on LoRaWAN_AT_Slave exmaple. But when I try to do this, I can't choose USART1 on Middleware->LORAWAN->VCOM parameter in STMCubeMX (see screenshot).I don't understand why, thus in LoRaWAN_End_Node, it i...
Hi.I tried to use TAG_OTA_END and TAG_OTA_START from BLE_HeartRate_ota ST project the same it is used in this project to verify the FOTA operation was finished successfully.I added both, PLACE_IN_SECTION in my ble file and also I added this tags in t...
Hi, I have a problem with USB CDC on STM32WB55CE,My Project version is v1.13.& ble stack(stm32wb5x_BLE_Stack_basic_fw V1.15.0)it's all good on WB55CG(1M)but when I use WB55CE(512K)my CDC can work with no ble stack,and it will failure with stack, My c...

Hy, I'm currently working on a project that requires CAN and that information needs to be sent via wireless, for that reason, I chose the NUCLEO stm32WL board. To make the CAN work I have to use the MCP2515 module, that converts CAN to SPI so that th...
