Hello I have two STM32WL55JC2 boards and I would like to run the PingPong DualCore example available in this WL package folder : I run the .project file on the STM32 IDE and I get this: After adding several missing .h files I manage to flash to the b...
How to send multi packet and is there any example?
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)?
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.
Resolved! How to do factory reset for stm32wb55VG6TY 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...
How to create sequential files on an SD card
