Hello,I added a new characteristic to the P2P_Server application that is a, CHAR_PROP_WRITE and GATT_NOTIFY_WRITE_REQ_AND_WAIT_FOR_APPL_RESP = Yes, all other notifications are set to No. The UUID = 50 50. I added the processing of the incoming char...

Hello, I have a STM32WB55RE connected to a CAN bus. I'm receiving the CAN data via the Main function using polling. When a message is received (250K Baud Rate) I want to forward that data to the BLE stack so I can send it to another STM32WB55RE. I...

I have two custom STM32WB55 boards that I initially started with the P2P_Client/Server projects. I have the two devices communicating with each other. Once the communication is established, the notification characteristic is enabled from the P2P_Cl...

Still trying to get USBX to work, I can now get data out to Putty but it's all garbage and after each send it "dings" (very annoying). I used the H5 example to get it working, last hurdle I guess. Putty is set to 115200, 1 stop bit, 8 data bits jus...

I'm just starting my journey in the ST BLE world, but I think that's handled in the aci_gap_set_discoverable method. I find I spend most of my time searching entire projects (Ctrl+a+a) and it helps me to match things up from one of the samples to wh...

Thank you, I will investigate using a circular buffer. Thank you for your help!

Hello,I'm initially just trying to get the data over to the Bluetooth stack. I was thinking a queue would suit my purposes, but the sequencer doesn't have any queuing mechanism. I could use a global variable to pass the data but that's troublesome ...

Hello,Thank you for your response. The CAN bus data is being collected via a MCP2515-I/ML and MCP2562T-E_MF. I'm receiving the CAN bus data correctly. Just can't figure out the best way to transfer that data to the BLE stack to be sent. I'm using...

I've gotten nowhere with this. I used the same cable and port on a f446 Nucleo board, NOT using USBX and the string is written out to the terminal window just fine. Try USBX on the U535 and it's all garbage. And one other thing I noticed, if I don...
