Problem with new BLE support for Raspberry Pico W and platform.io

[seldom-c]

Hello,

I'm having a problem compiling the latest CS git to test BLE support with my Raspberry Pico W. I haven't been able to understand the cause of the problem after several hours so i'm posting here in case you can reproduce. The problem happens trying to compile a test project with platform.io:

Compiling .pio/build/raspicow/lib8cf/ArduinoBLE/utility/HCICordioTransport.cpp.o
.pio/libdeps/raspicow/ArduinoBLE/src/utility/HCICordioTransport.cpp:25:10: fatal error: driver/CordioHCITransportDriver.h: No such file or directory
25 | #include <driver/CordioHCITransportDriver.h>

If I "fix" include paths then the problem arises during linking:

/Users/hku/.platformio/packages/toolchain-gccarmnoneeabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld: .pio/build/raspicow/lib8cf/libArduinoBLE.a(HCICordioTransport.cpp.o): in function HCICordioTransportClass::end()': HCICordioTransport.cpp:(.text._ZN23HCICordioTransportClass3endEv+0x20): undefined reference to ble_cordio_get_hci_driver()'
/Users/hku/.platformio/packages/toolchain-gccarmnoneeabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld: HCICordioTransport.cpp:(.text._ZN23HCICordioTransportClass3endEv+0x24): undefined reference to `ble::CordioHCIDriver::terminate()'
...

I'm using the latest versions of platform.io, Arduino BLE and such. Also the bluetooth stack is enabled during compilation:

Thanks in advance for any feedback you may have on this issue

If you have the Pi Pico W board selected, PlatformIO should set the ARDUINO_RASPBERRY_PI_PICO_W macro.
This causes Control Surface to select the correct Bluetooth stack. Otherwise, it falls back to the ArduinoBLE library.

It appears that the ArduinoBLE library is not supported by the arduino-pico core, which is why you're seeing the errors you posted, but this is not the main cause.

Please post the PlatformIO configuration you're using.

I can't seem to reproduce the issue. Here's the platformio.ini file I'm using:

[env:pico]
platform = https://github.com/maxgerhardt/platform-raspberrypi.git
board = rpipicow
framework = arduino
board_build.core = earlephilhower
board_build.filesystem_size = 0m
build_flags = -DUSE_TINYUSB -DPIO_FRAMEWORK_ARDUINO_ENABLE_BLUETOOTH
lib_deps = https://github.com/tttapa/Control-Surface.git#main
lib_ignore = MIDIUSB
build_type = release

Oh right, it compiles using your config, thank you. I was actually trying to use the official arduino-pico core as you said. This is the last platform.io config I was testing, but I got into several other compilation problems with btstack:

[env:raspicow]
platform = raspberrypi
board = pico
framework = arduino
build_flags = -DPIO_FRAMEWORK_ARDUINO_ENABLE_BLUETOOTH -DARDUINO_RASPBERRY_PI_PICO_W -DENABLE_BLE
upload_port = /Volumes/RPI-RP2/
monitor_speed = 115200
lib_deps =
https://github.com/tttapa/Control-Surface.git#main
https://github.com/bluekitchen/btstack.git
https://github.com/Leont/crypt-rijndael.git
kmackay/micro-ecc
lib_ignore = MIDIUSB

i'll be doing my test using the earlephilhower core for now, but let me know if you want me to do more testing to make it work with arduino-pico core

Thanks again

The link you posted in your original message is part of the earlephilhower core documentation. That's also what I based my configuration on.

You seem to be using the https://github.com/platformio/platform-raspberrypi platform, which (as far as I can tell) does not support the RPi Pico W (only the RPi Pico and the Arduino Nano RP2040 Connect, see https://github.com/platformio/platform-raspberrypi/tree/develop/boards).
