Hi,the same question was already reported in this topic some years ago.https://community.st.com/s/question/0D50X00009Xkh0DSAR/bluenrg-missing-le-advertising-report-eventI have the same problem: if I use HCI standard commands, (HCI_LE_SET_SCAN_PARAMET...

I'm using the P2P demo for the X-nucleo-PLM01A1 and I want to change the frequency of the modulation from 86000 to 132000 kHz. Can anyone help me because I don't find the solution

Resolved! Can't detect bluetooth from B-U585I-IOT02A.

I am using BLE_AT_CLIENT example from STM32CubeIDE 1.7.0 but nothing detected either on ST BLE SENSOR app or on my computer/smartphone normal bluetooth scan. I have 2 B-U585I-IOT02A and both give the exact same error message on teraterm. Also here is...

Is the MT4100SM6F UL Recognized?

IAR ARM 8.50.x can't find the processor BlueNRG-LP

Does the DK example only work under IAR ARM 8.4.1?

Resolved! What means the marking code below the part number of this IC?

I have this IC with the part number 3485EB, found the datasheet but it doesn't explain what this marking code below the part number (M2123) means. What does that mean?
