"Too few arguments to function 'esp_err_t esp_ble_gattc_open(esp_gatt_if_t, uint8_t*, esp_ble_addr_type_t, bool)'" when trying to run any of the examples

[pgrlopes]

Hey guys.

I've been looking to get my esp32 ble component to send some information to my smartphone for the past couple days and I'm now trying to use this repository as a base for my code. However, none of the examples for the server or client work because of the error in the title.

I've googled it and found some answers pointing to some errors introduced with new updates to the libraries and that I should revert to a previous version but I'm new here and I just don't know how to do it.

Any help would be appreciated.
Thank you.

Arduino-ide or esp-idf?

[pgrlopes]

Sorry, i'm using arduino IDE

[chegewara]

If you are working on windows then go to folder:
C:\Users\USER\Documents\Arduino\hardware\espressif\esp32
execute command:
git status

if you get result other than:

On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean

then execute:

git pull
git submodule update --init

Maybe there is something i am missing because i did not check before update, but with updated stack first example i tested (BLE_server) works.

Yeah I had tried this solution previously as it was suggested in another thread and it didn't work. I tried it now and it's working now. My issue is that when I installed the esp32 modules it wasn't on the c:\users directory but instead in the arduino ide directory itself (C:\Program and files\Arduino...) and the libraries were in conflict.

Could you just tell me what is the directory that I should be using for the esp32 folder? Is it the C:\users one?

Thank you very much for your help.

[chegewara]

It does not matter where you install Arduino-ide, i have it installed in E:\Program Files (x86)\Arduino, the point is that arduino is keeping by default files here:
C:\Users\USER\Documents\Arduino

You can change it in Preferences->sketchbook location. Now in this folder you have hardware subfolder with esp32 subfolder and so on. More important is that you can install BLE library with arduino-esp32, then it will be in this folder by default:
C:\Users\USER\Documents\Arduino\hardware\espressif\esp32\libraries\BLE and you will need to update it from time to time with procedure from this post, or you can install it from Plugins manager or zip file.

[pgrlopes]

Yeah that's the thing, my ESP32 folder is actually in the arduino ide directory hence all the issues, I was applying the solutions to the users/arduino folder but forgetting about the libraries not updated in the esp32 folder. Thank you once again for the help

Just hit the same issue. I did not use Git, just the regular install. Any thoughts on how to correct?

Got it, was outdated ESP lib./

The demo consume a huge amount of memory. Is that expected?

Sketch uses 1232701 bytes (94%) of program storage space. Maximum is 1310720 bytes.
Global variables use 46624 bytes (15%) of dynamic memory, leaving 248288 bytes for local variables. Maximum is 294912 bytes.

[chegewara]

Yes, i dont know why, it was about 900kB some time ago, but now its a lot more. You can change Partition to No OTA

[MajicCat]

Is there a stable build with the smaller profile  that can be pulled and compared?

I'm working with the esp-idf and am getting that error - any suggestions?

EDIT sorry, edited by mistake, wanted to quote

[chegewara]

I'm working with the esp-idf and am getting that error - any suggestions?

Yes, after a year its so many changes in esp-idf so i suggest to open new issue and provide esp-idf version you are using and logs.

@pana216 @chegewara I fixed by changing lines in BLEDevice.cpp with:

line 494: esp_err_t errRc = esp_ble_gap_update_whitelist(true, *address.getNative(), BLE_WL_ADDR_TYPE_PUBLIC); // True to add an entry.

line 508: esp_err_t errRc = esp_ble_gap_update_whitelist(false, *address.getNative(), BLE_WL_ADDR_TYPE_PUBLIC); // False to remove an entry.

that last argument can be public or random, idk what it does though

This resolved to some other errors and warning, but these were easily to handle, just googled and fixed them. Thank you very much I really appreciate it!!
