Wifi/BLE Paxcounter Project with ESP32 boards

pe1mew · November 20, 2018, 6:34pm

With the latest version of PAX counter from github I cannot compile the code.

I do get this error:

src\wifiscan.cpp: In function 'void wifi_sniffer_packet_handler(void*, wifi_promiscuous_pkt_type_t)':
src\wifiscan.cpp:16:9: error: 'wifi_ieee80211_packet_t' does not name a type

Can anyone point me in a direction how to solve this?

Thanks in advance.

Sorry, the same problem at the moment. Worked a few days ago.

Right, but why this Error:

I had to add the include path to wifiscan.h to remove these errors and produce new ones:
My addition to include to platformio.ini:

build_flags =
    -include include/wifiscan.h

Now I get these errors:

I am lost.

Unfortunately i cannot reproduce this in my IDE (Windows 10, Visual studio code, Platformio), code in current repo master branch (commit b921731) compiles without errors.

I made some changes in platformio.ini, i assume that this causes trouble may be with IDEs using Linux or Atom?

Please open issue, maybe someone else can fix this. I think it’s a minor detail, maybe a path setting in platformio.ini

New features in Paxcounter v1.6.82:

now supports Bosch BME680 sensor (temp, pressure, humidity, voc).
Next release shall also report BME680 IAQ (indoor air quality) scale value.
now has timesync for the node implemented, primary using GPS time, if not present using time sync over LoRaWAN network*

*) requires MAC command DevTimeReq, not supported on TTNv2 stack

I am using Windows 10, Atom, Platformio.

Sure, something is seriously messed-up and therefore the project is likely no more platform/IDE independant.

My workaround (dirty but effective):
1: In platformio.ini i added to the build_flags::

-include include/wifiscan.h

2: In the file WMath.cpp (my path: C:\Users<username>.platformio\packages\framework-arduinoespressif32\cores\esp32) I uncommented the following lines as these seem to conflict with the declaration and implementation of the arduino libraries:

// unsigned int makeWord(unsigned char h, unsigned char l)
// {
//     return (h << 8) | l;
// }

Now it compiles and I can continue.

I’ll make a issue and workaround so the real experts can work on a more solid solution.

Paxcounter v1.6.82 on TTGO T-BEAM with additional Bosch BME680 MEMS I2C sensor Screenshot_20181121-081744

Verkehrsrot · November 21, 2018, 7:20am

But this won’t be the root cause.
Paxcounter code itself is not using WMath.cpp, must be some sort of side effect.

pe1mew · November 21, 2018, 7:35am

Likely.

Issue is applied to the repo: Cannot compile on Windows 10, Atom, Platformio · Issue #206 · cyberman54/ESP32-Paxcounter · GitHub

Amedee · November 21, 2018, 9:45am

Out of curiosity I did a fresh install on Linux (no ide) and it kind of compiled well.

Issues:

BME680 code breaks the build (you need to add the Adafruit libs)
It does not work well on case sensitive filesystems (I’ll file an issue for that)

But aside that it compiled correctly

Verkehrsrot · November 21, 2018, 10:44am

For BME680 on your device you need to add this line in platformio.ini in the device environment:

lib_deps =
…
${common.lib_deps_sensors}

Or use environment generic, which incorporates all features.

Amedee · November 21, 2018, 10:49am

Yes, i have seen that. The thing is that currently it requires the lib to compile (with the default settings)…

There is a also a missing include for TimeLib.h from lorawan.cpp

Verkehrsrot · November 21, 2018, 10:52am

The Adafruit lib will be removed in next release, moving to precompiled Bosch BSEC lib.

go123 · November 21, 2018, 10:04pm

Excuse me, is there a complete version that can be compiled without errors? The current one does not work. On none of my computers (IDE (Windows 10, Visual studio code, Platformio

Verkehrsrot · November 22, 2018, 6:05am

I still cannot reproduce these errors, please open issue and give more details, thx

Verkehrsrot · November 22, 2018, 8:00pm

I reverted a change made with one of latest commits in platformio.ini.
User which had compile errors, could you please try again with current version in master branch and report here? Thx.

pe1mew · November 22, 2018, 8:43pm

Sorry, but a clean download from github produces the same error like before.

Verkehrsrot · November 22, 2018, 9:07pm

Thanks for testing!
Allright, i have no idea then. Still cannot reproduce the issue in my environment.
