Platformio and MySensors development branch

[gerritv]

Is anyone successfully using Platformio with development branch?

I am using platformio to do my Arduino development. Works fine if I stick to the Master branch of MySensors (library #548). But if I try to use the Development branch (manually installing it as a library for Platformio) then I get a lot of compile problems that frankly make no sense. E.g. compiling the MQTT demo (GatewayW5100MQTTClient) I get errors in MyGatewayTransportEthernet that EthernetServer and EthernetClient are not a type, aka they were not found in an include somewhere.
http://platformio.org for those wondering.

@gerritv I will answer the question myself.

The directory layout of MySensors is a bit unusual, requires the following layout in platformio.ini

[platformio]
lib_dir = ../lib

[env:nanoatmega328]
platform = atmelavr
framework = arduino
board = nanoatmega328
build_flags = -I../lib/MySensors
lib_ignore = MySensors

The directory layout I use is:
Top level, a directory called lib with the contents of MySensors development branch. Inside this top level directory you have your various projects relating to this Solution:
A directory for your sensor node sketch, e.g, LivingRoomNode which contains the Platformio directory and the above info in its ini file
A directory for your gateway, with the same library parameters

The result is a solution with multiple source projects pointing at the same MySensors library.

Platformio is a great way to develop ESP8266/Arduino etc code. Also Platformio works very well with Visual Studio 2015 CE (this is what I build my MySensors nodes and gateways with).

I am trying to do the same but can't get a compile to work. I created a directory structure similar to the one you describe. In my gateway /src directory I copied the GatewayESP8266MQTTClient.ino file and used the same parameters for platformio.ini as in your example:

[platformio]
lib_dir = ../lib

[env:nodemcu]
platform = espressif
framework = arduino
board = nodemcu
build_flags = -I../lib/MySensors
lib_ignore = MySensors

However, when I compile I get this error:

src/tmp_ino_to.cpp:129:22: fatal error: MySensor.h: No such file or directory
#include <MySensor.h>
^
compilation terminated.

The sketch otherwise compiles perfectly fine under the Arduino IDE.

I'm sure it's a configuration issue somewhere. Can you expand a bit more on your file structure. Did you need to do any customization of PlatformIO to make it see the MySensors library?

[gerritv]

@Iyad-Nahas your .ino file must be in the src directory. I was compiling my ESP8266 gw yesterday with no issues.
I didn't need any customization of platformio. I am using 2.8.5

[gerritv]

@gerritv Sorry, just re-read your msg and you already have the .ino in correct place.
Are you certain there is no .ino outside the src directory? Are you using the development version of the libraries as well as the example from it?
I recently changed my MySensors lib directory to be direct from Git development branch so the platformio lines are a bit different now (but same idea)

[platformio]
lib_dir = ../MySensorsLib/libraries

[env:nodemcuv2]
platform = espressif
framework = arduino
board = nodemcuv2
build_flags = -I../MySensorsLib/libraries/MySensors
lib_ignore = MySensors
targets = upload

Well, after some trial and error I ended up with just adding the build_flags option with the path to the MySensors library and now building works fine.

Here's my final platform.ini:

[env:nodemcu]
platform = espressif
framework = arduino
board = nodemcu
build_flags = -I../lib/libraries/MySensors

Now to figure out why the auto upload doesn't work. If I upload manually it works fine, but when I add "targets = upload" it keeps trying to connect then times out with an error. No big deal though. I don't mind uploading manually.

Thank you for your help.
