I'm busy debugging the RF conditions around my LoRaWAN installation.I get a lot of variance in both RSSI and SNR (+-10dB/+-6dB) and am trying to find it's source.In the absence of an SDR and other equipment, is it possible to read and report RSSI an...
HiI just bought a B-L4S5I-IOT01A Discovery kit.Confession: I am completely new to ST, and I reckon I have a mountain of learning to do in a short time.However, I just read the blurb on the back of the kit and it essentially says: 1. Verify the jumper...
The errata sheet ES0500 - Rev 4 mentions a workaround for 2.8.3 DMA stream locked when transferring data to/from USART where bit 20 of register DMA_SxCR shall be set. This register is not mentioned in the reference manual and not in the respective he...
Hi, I've got an STM32WB15CCU6 on a custom board and am currently trying to get it to boot from Flash memory after programming it with the STM Cube IDE.Debugging a program in the IDE works perfectly fine, but if I flash it to my microcontroller (using...
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...
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...
