The solution of BLE 5.1 direction finding
Do you have a solution of BLE 5.1 direction finding? If yes, where can I download it? If no, do you plan to provide it or not?

Details Bluetooth 5.0 implementation of the ST
I am interested in the implementation of Bluetooth 5.0 from ST. In describing some of the chips I've seen that meets Bluetooth v5.0 specification. But it is not clear whether there is a "Long Range" support.Where I can see this information?
ST Manual UM2496 "...BlueST protocol.." indicates a 2 byte timestamp for many of the characteristics. I cannot find a reference which decodes this format?
I understand the data format to be little endian and can someone show where the format is explained? As an example please decode C7 38 which occurred around 17:26:58.Thanksralph
s2-lp narrowband settings
Hi EnricoCan you please suggest us the correct values for data rate, deviation and channel filter for the sp-l2 in a narrowband application?How narrow can we go?Also in your schematic you use a trimmer for calibration .Why? Isn’t the tcxo precise eno...
Manual Control of VBUS_EN_SNK of STUSB4500?
Hi,we want to have a possibility to disconnect the USB-C supply manually.Can we use the VBUS_EN_SNK signal and disable the corresponding mosfet manually?The datasheet is somehow unspecific.Is the VBUS_EN_SNK signal undriven when we set the device via...
blueNRG Master/Central Library conn_length
I'm working on a central BLE device. I'm having some trouble with the sensor and the hub not being in sync. It looks like that the central device wakes up to late, every 3rd wake event the central wakes up at the right time and a PDU is sent/received...
SPBTLE-RF direct mode
Hello, we have developed a device based on SPBTLE-RF and stm32L452.To certify the device we have to operate BLE modules in direct mode. If I understand correctly DT0069, hci is only on SPI and we should forward on the UART. Are there any code example...
Question regarding the fall time of STM3117.
In the datasheet for interface with STM3117 using the i2c line, the minimum criteria for fall time is 20ns is given.Why these minimum criteria for fall time is given?What will happen if clock line fall time less than 20ns?Please explain.
