# Arduino Core for STM32WB based boards
2+
3+
## What is it ?
4+
5+
ArduinoCore-stm32wb is targeted at ultra low power scenarios, sensor hubs, with BLE connectivity.
6+
7+
8+
## Supported boards
9+
10+
### Tlera Corp
11+
* [Firefly-STM32WB55CG](https://www.tindie.com/products/TleraCorp/firefly-stm32wb55-development-board)
12+
13+
### STMicroelectronics
14+
* [NUCLEO-WB55RG](https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/stm32-nucleo-expansion-boards/p-nucleo-wb55.html)
15+
16+
17+
## Installing
18+
19+
### Board Manager
20+
21+
1. [Download and install the Arduino IDE](https://www.arduino.cc/en/Main/Software) (at least version v1.6.13)
22+
2. Start the Arduino IDE
23+
3. Go into Preferences
24+
4. Add ```https://grumpyoldpizza.github.io/ArduinoCore-stm32wb/package_stm32wb_boards_index.json``` as an "Additional Board Manager URL"
25+
5. Open the Boards Manager from the Tools -> Board menu and install "Tlera Corp STM32WB Boards"
26+
6. Select your STM32WB board from the Tools -> Board menu
27+
28+
#### OS Specific Setup
29+
30+
##### Linux
31+
32+
1. Go to ~/.arduino15/packages/grumpyoldpizza/hardware/stm32wb/```<VERSION>```/drivers/linux/
33+
2. sudo cp *.rules /etc/udev/rules.d
34+
3. reboot
35+
36+
##### Windows
37+
38+
###### STM32 BOOTLOADER driver setup for Tlera Corp boards
39+
40+
1. Go to ~/AppData/Local/Arduino15/packages/grumpypoldpizza/hardware/stm32wb/```<VERSION>```/drivers/windows
41+
2. Right-click on ```STM32Bootloader.bat``` and select ```Run as administrator```
42+
43+
###### ST-LINK V2.1 driver setup for NUCLEO boards
44+
45+
1. Plugin NUCLEO board
46+
2. Download and install [ST-Link USB Drivers](http://www.st.com/en/embedded-software/stsw-link009.html)
47+
48+
### From git (for core development)
49+
50+
1. Follow steps from Board Manager section above
51+
2. ```cd <SKETCHBOOK>```, where ```<SKETCHBOOK>``` is your Arduino Sketch folder:
52+
* OS X: ```~/Documents/Arduino```
53+
* Linux: ```~/Arduino```
54+
* Windows: ```~/Documents/Arduino```
55+
3. Create a folder named ```hardware```, if it does not exist, and change directories to it
56+
4. Clone this repo: ```git clone https://github.com/grumpyoldpizza/ArduinoCore-stm32wb.git TleraCorp/stm32wb```
57+
5. Restart the Arduino IDE
58+
59+
## BLE / Wireless stack firmware installation
60+
61+
STM32WB uses encrypted/signed firmware images for the BLE stack. Please flash the ```FWUpdate``` sketch under the ```STM32WB``` examples before using BLE. The update will take up few seconds/minutes. During that time the LED will stay on, while the serial monitor will say disconnected. When done the LED will blink if the update was succesful, or simply be turned off if an error was encountered. The serial monitor should pop up again and report back the newly updated firmware versions. The ```FWInfo``` sketch can be used to verify what version is installed. At this time it should report back 1.10.0 for the BLE stack.
62+
63+
## Recovering from a faulty sketch for Tlera Corp Boards
64+
65+
Sometimes a faulty sketch can render the normal USB Serial based integration into the Arduindo IDE not working. In this case plugin the STM32WB board and toggle the RESET button while holding down the BOOT button and program a known to be working sketch to go ack to a working USB Serial setup.
66+
67+
## Credits
68+
69+
This core is based on the [Arduino SAMD Core](https://github.com/arduino/ArduinoCore-samd)
