Building firmware with modified platformio.ini

[DaniilMir]

Hello Community,

I'm trying to make a Tasmota build with SSL and IR support, but for some IR protocols only.

Original discussion : arendst/Tasmota#13202 (reply in thread)

I tried connecting to the docker container's shell as per guide : https://github.com/benzino77/tasmocompiler/blob/master/ADVANCED.md

After that I've tried adding the following flags:
-D_IR_ENABLE_DEFAULT_=false -DDECODE_SYMPHONY=true -DSEND_SYMPHONY=true -DSEND_RAW=true

into the build_flags section in platformio.ini and platformio_tasmota_env.ini
After running a compile from UI - those settings were lost.

Questions :

1. Is there an option to persist these changes in the build_flags? I mean to change flags and to compile a customized firmware.
2. If yes how to do it properly for a generic ESP8266 template ?

To persist changes you need to modify the file AvailableBoards.js
It is rather self describable. I think you need to look at esp8266generic board definition and platformio_entries section.

Thank you @benzino77 for your advise.
I found this file and modified it as following :

AvailableBoards.js

name: 'esp8266generic',
chip_type: 'esp8266',
description: 'Generic',
default: true,
show: true,
platformio_entries: {
  build_flags: -DDECODE_SYMPHONY=true
               -DSEND_SYMPHONY=true
               -DDECODE_SONY=true
               -DSEND_SONY=true
               -DSEND_GREE=true
               -DDECODE_GREE=true
               -DDECODE_ELECTRA_AC=true
               -DSEND_ELECTRA_AC=true
               -DDECODE_MIRAGE=false
               -DDECODE_AIRTON=false
               -DDECODE_AIRWELL=false
                . . . . . . 
               -DSEND_SANYO_AC88=false
               -DSEND_SHARP=false
               -DSEND_SHARP_AC=false
               -DSEND_SHERWOOD=false
               -DSEND_TCL112AC=false
               -DSEND_TCL96AC=false
               -DSEND_TECHNIBEL_AC=false
               -DSEND_TECO=false
               -DSEND_TEKNOPOINT=false
               -DSEND_TOSHIBA_AC=false
               -DSEND_TOTO=false
               -DSEND_TRANSCOLD=false
               -DSEND_TROTEC=false
               -DSEND_TROTEC_3550=false
               -DSEND_TRUMA=false
               -DSEND_VESTEL_AC=false
               -DSEND_VOLTAS=false
               -DSEND_WHIRLPOOL_AC=false
               -DSEND_WHYNTER=false
               -DSEND_XMP=false
               -DSEND_ZEPEAL=false,
},
platformio_env_name: 'tasmota',
tooltip: 'stepFeaturesBoard8266Tooltip',
include_features: ['rules'],

Unfortunately it didn't work with the resulting build size.
Maybe I did something wrong with definition.
The same config added into platformio in the desktop environment works as expected.

availableBoards is a JS object. You cannot use just literals. You have to close it with single quotes. Something like:

platformio_entries: {
  build_flags: '-DDECODE_SYMPHONY=true -DSEND_SYMPHONY=true -DDECODE_SONY=true -DSEND_SONY=true -DSEND_GREE=true <rest of flags>'
}

or it you have to use multi line notation, you should try to use something similar to:

platformio_entries: {
  build_flags:
    '-DDECODE_SYMPHONY=true\n' +
    '\t-DSEND_SYMPHONY=true\n' +
    '\t-DDECODE_SONY=true\n' +
    '\t-DSEND_SONY=true\n' +
    '\t-DSEND_GREE=true\n',
},

You can always check how platformio_override.ini and user_config_override.h files look like by downloading them after compilation. Those buttons will allow you to download those files to your local machine:

You can also check them directly in /tmp/Tasmota and /tmp/Tasmota/tasmota directory (on gitpod instance)
Then you can review what "magic" TasmoCompiler use to compile your binary (TasmoCompiler tweaks Tasmota by adding things to those two files only - NOTHING else ).
