====NUCLEO-WB15CC====
{{:boards:wb15cc.jpg?100}} {{boards:btapp.jpg?100}}
This board contains a dual core processor with a Bluetooth radio.
The primary processor is for the user application and
the secondary processor runs a firmware blob to control the radio.
It's not possible to utilise the radio directly since there are no
docs for that.
WARNING: There is an option byte called ESE on this board, it you
disable it the board will refuse to operate (untested).

===Firmware upgrade services===
FUS is used to install the software stack on the co-pro.
The STM32CubeProgrammer desktop application provides a FUS page where the you can `Read FUS infos'.
The factory default `infos' are as follows.
^Info^Value^
|FUS State | FUS_IDLE|
|FUS Status | FUS_NO_ERROR|
|FUS Version | v1.2.20|
|Stack Version| ------|
|FUS Operator | v3.1.0|
If the FUS version reads all zeros you must `Start FUS' and try again.
NB This process appears to erase the user firmware on the device to operate.
===Firmware upgrade blobs====
Here is the list of blobs for V1.18.0 / 30-Oct-2023
^Wireless Coprocessor Binary^stm32wb1x(320K)^Version^
|stm32wb1x_BLE_HCILayer_extended_fw.bin |0x0802D000|V1.18.0|
|stm32wb1x_BLE_HCILayer_fw.bin |0x08032000|V1.18.0|
|stm32wb1x_BLE_HCI_AdvScan_fw.bin |0x0803D000|V1.18.0|
|stm32wb1x_BLE_LLD_fw.bin |0x0803F800|V1.18.0|
|stm32wb1x_BLE_Stack_full_extended_fw.bin|0x08018800|V1.18.0|
|stm32wb1x_BLE_Stack_full_fw.bin |0x08021000|V1.18.0|
|stm32wb1x_BLE_Stack_light_fw.bin |0x08029000|V1.18.0|
|stm32wb1x_Safeboot_fw.bin|0x08044000|V2.0.0|
Mostly these are bluetooth blobs and the final blob is
used to reset the option bytes.
The Android app demos work with stm32wb1x_BLE_Stack_full_fw.bin and STM32CubeMX allows selection between full and light for building new projects.
===Upgrade procedure===
The following procedure was followed from the docs and it appears to work
correctly once a demo hex file is also loaded.
Fetch blobs
mkdir -p /mnt/c/ST
cd /mnt/c/ST
wget "https://github.com/STMicroelectronics/STM32CubeWB/archive/refs/heads/master.zip"
unzip STM32CubeWB-master.zip
This upgrades firmware to stm32wb1x_BLE_Stack_full_fw.bin
Browse to
/mnt/c/ST/STM32CubeWB/tree/master/Projects/STM32WB_Copro_Wireless_Binaries/STM32WB1x
Select
stm32wb1x_BLE_Stack_full_fw.bin
It should say STACKV 1.18.0
Enter start address from table
0x08021000
Now press firmware upgrade and after start the wireless firmware.
===Demo firmware===
To program the device with a user application use the command line utility not the desktop app.
A few demos exist for the the Android app named "ST BLE Sensor"
==P2P server demo==
==Program==
A pre-built hex file can be programmed, else the application built from a [[https://wiki.st.com/stm32mcu/wiki/Connectivity:STM32WB_BLE_STM32CubeMX|guide]] for STM32CubeMX.
"/mnt/c/Program Files/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/STM32_Programmer_CLI.exe" -c port=SWD reset=HWrst -q -w BLE_p2pServer_reference.hex -v -hardRst
The hex file can be found in the Applications directory for the board along with the blobs downloaded above.
==Console==
Connecting a console via ST-LINK show the following dialog when booting, connecting and turning the blue led on and off.
$ picocom --imap lfcrlf --quiet -b 115200 /dev/ttyS12

The UUID "0000fe40-cc7a-482a-984a-7f2ed5b3e58f" is used to communicate with the p2pServer STM32_WPAN application firmware.
The handles that are known to operate p2pServer are 0x0E and 0x11
Handle 0x0011 turns button notification on and off and 0x0E is the blue LED.
For example, to turn on the LED:
char-write-cmd 0x0E 0x01
The console log was
-- GATT : LED CONFIGURATION RECEIVED
-- P2P APPLICATION SERVER : LED1 ON
NB char-write-cmd above works in interactive mode but not otherwise. char-write-req fails either way since this is setup in the firmware as write without a response.
==Python==
See [[tools:bluetooth#python|this]] example code to operate the p2pServer demo.
