Which Tasmota pre-compiled build is best to use with these examples?

[LucidEye]

I am trying to use some of these Berry examples to learn more about BLE for a project I am building.
However I don't seem to be getting any functionality out of the Berry examples when using the "plain" Tasmota32 pre-compiled build.
Are these examples meant to be used with the Tasmota32-Bluetooth pre-compiled build?
Or is there something we need to edit/activate in the code and recompile to take advantage of these Berry scripts?
Sorry, I'm a very novice coder, and Berry is about as obscure as it gets so I don't understand why I can't seem to make these work.
Specifically, I'd like to have Tasmota connect to a BLE device that is already setup as a server (a Pinecil v2 soldering iron) and be able to display all of the sensor data from the Pinecil in the Tasmota web interface like you can with most sensors. Or even better still, have the data be displayed on a lvgl LCD device such as an ESP32-CYD (cheap yellow display). Is this possible? The Pinecil is running IronOS which gives each sensor reading it's own UUID, or it also broadcasts a binary blob that contains all of the sensor data in an array.
Any advice would be appreciated.
Thank you.

All these examples need a firmware with full Bluetooth Low Energy support, which is activated like that:

[env:tasmota32-mi32]
extends                     = env:tasmota32_base
build_flags                 = ${env:tasmota32_base.build_flags}
                              -DFIRMWARE_BLUETOOTH
                              -DUSE_MI_EXT_GUI
                              -DCONFIG_BT_NIMBLE_NVS_PERSIST=y
                              -DOTA_URL='""'
lib_extra_dirs              = lib/libesp32, lib/libesp32_div, lib/lib_basic, lib/lib_i2c, lib/lib_div, lib/lib_ssl
lib_ignore                  = Micro-RTSP

The magic line is: -DUSE_MI_EXT_GUI
You will find more demo build sections in: https://github.com/arendst/Tasmota/tree/development)/platformio_tasmota_cenv_sample.ini

After activating Bluetooth with so115 1, you can try to find the Pinecil with the builtin scanner by:
MI32Option5 1 - shows every BLE device, not only Xiaomi and the likes
MI32Option4 1 - could be helpful, by using active scanning, but depends on the device

After reading through this example:
https://github.com/joric/pinecil/blob/main/index.html
I would be very surprised, if this can NOT work with Tasmota.

Please try the first steps from above to check for basic compatibility, after that I can help you with the rest.

Sorry I haven't replied sooner,been dealing with other things.
As I mentioned, I am a very novice programmer, so can you please add some clarification to your reply?

Is this something I need to do in a code editor such as Arduino IDE or VSCode? I read that if I want to enable different features simultaneously, like displays and BLE, that I need to start with the base Tasmota32 firmware and NOT with one of the already modified pre-compiled builds. So I would need to enable both the BLE and the display support in the code and then re-compile?

All these examples need a firmware with full Bluetooth Low Energy support, which is activated like that:

[env:tasmota32-mi32]
extends                     = env:tasmota32_base
build_flags                 = ${env:tasmota32_base.build_flags}
                              -DFIRMWARE_BLUETOOTH
                              -DUSE_MI_EXT_GUI
                              -DCONFIG_BT_NIMBLE_NVS_PERSIST=y
                              -DOTA_URL='""'
lib_extra_dirs              = lib/libesp32, lib/libesp32_div, lib/lib_basic, lib/lib_i2c, lib/lib_div, lib/lib_ssl
lib_ignore                  = Micro-RTSP

I have already confirmed that I can "see" the BLE advertisement from the Pinecil in the console when using the Tasmota32-Blurtooth.bin pre-compiled build, I just don't understand how to pair and connect to the Pinecil from Tasmota.

After activating Bluetooth with so115 1, you can try to find the Pinecil with the builtin scanner by: MI32Option5 1 - shows every BLE device, not only Xiaomi and the likes MI32Option4 1 - could be helpful, by using active scanning, but depends on the device

I am familiar with the PineSAM app, which is basically the same thing as this code example from joric's github project, but I still have no idea how to use this to read the data blob in Tasmota.

After reading through this example: https://github.com/joric/pinecil/blob/main/index.html I would be very surprised, if this can NOT work with Tasmota.

I destroyed the link somehow:
https://github.com/arendst/Tasmota/tree/development/platformio_tasmota_cenv_sample.ini

So you already have the correct firmware flashed?
You should be able to see a dashboard and with mi32option5 1 there should be a little widget with the advertisement of the Pinecil including the MAC address.

If that works, I can try to guide you to the rest of the process.

I'm sorry, again I am not a programmer, can you please explain things to me with more detail.

I don't understand what you mean by this...

All these examples need a firmware with full Bluetooth Low Energy support, which is activated like that:

[env:tasmota32-mi32]
extends                     = env:tasmota32_base
build_flags                 = ${env:tasmota32_base.build_flags}
                              -DFIRMWARE_BLUETOOTH
                              -DUSE_MI_EXT_GUI
                              -DCONFIG_BT_NIMBLE_NVS_PERSIST=y
                              -DOTA_URL='""'
lib_extra_dirs              = lib/libesp32, lib/libesp32_div, lib/lib_basic, lib/lib_i2c, lib/lib_div, lib/lib_ssl
lib_ignore                  = Micro-RTSP

The magic line is: -DUSE_MI_EXT_GUI

Is this something I need to edit in the basic Tasmota32 code and recompile?
If so, what file/s do I need to edit?
Is it easier to fork Tasmota to my own repository in GitHub and make the edits so Github Services can do the recompile to a .BIN file?
Or is it better for me to download all the Tasmota code and use VSCode with PlatformIO to make the edits?
If using VSCode with PlatformIO, I need to setup the IDE environment and need to know:
What ESP32 board do I need to add to the PlatformIO project for the Cheap Yellow Display (ESP32-CYD)?
What libraries do I need to add in the PlatformIO project?
Thank you for your patience while I try to get up to speed with understanding all of this.

No problem, everyone is a beginner at some point.
Then let‘s take the shortcut:

https://jason2866.github.io/Tasmota-specials/

Flash the following firmware: Tasmota32 MI BLE

[LucidEye]

I can not install "Tasmota32 MI BLE"
No matter what I try I get the following error...

I can install "Tasmota32 Bluetooth" from the main release install page https://tasmota.github.io/install/
I did not need to use the MI32Option5 1 command. I only needed to enable Bluetooth from the Configuration menu to see the Pinecil advertisement...

I can also see the Pinecil advertisement in the Console...

So next I guess I need to actually pair and connect to the Pinecil from Tasmota somehow?

[Staars]

Strange error. I will investigate.

Is there a download link for the Tasmota32 MI BLE .bin file so I can try to flash it OTA?

[Staars]

Sure:

You must download the correct binary for the exact ESP type, which is quite easily to infer from the name ( like C3, …).
