Problem running BLE examples

[diogoviannaaraujo]

Hi, im having some problems running any code with BLE.

After following all the guidelines on documentation about sdkconfig im getting this message when trying to mcconfig:

# cc modBLEServer.c.o
In file included from /Users/diogoviannaaraujo/Git/moddable/modules/network/ble/esp32/modBLEServer.c:27:0:
/Users/diogoviannaaraujo/Git/moddable/modules/network/ble/esp32/modBLEServer.c: In function 'xs_ble_server_initialize':
/Users/diogoviannaaraujo/esp32/esp-idf/components/bt/include/esp_bt.h:61:50: error: static assertion failed: "please enable bluetooth in menuconfig to use bt.h"
 #define BT_CONTROLLER_INIT_CONFIG_DEFAULT() {0}; _Static_assert(0, "please enable bluetooth in menuconfig to use bt.h");

Any ideia why that?

Edit1: Ive gone a little deeper and and found out that I could run make menuconfig on sdkconfig folder and configure build options, tried to re-save the sdkconfig file but got no luck either.

Edit2: Tryed rollbacking some versions of esp-idf, tried some commits back and even most of the releases, always the same error.

Hello -

The sdkconfig file shipped with the Moddable SDK disables BLE by default to avoid having to build all the BLE components in the ESP-IDF when the host app doesn't require BLE. Sorry for the inconvenience.

In order to enable BLE, you'll need to edit the $MODDABLE/build/devices/esp32/xsProj/sdkconfig file and then rebuild the Moddable app with mcconfig. Please refer to the BLE documentation here for details:

https://github.com/Moddable-OpenSource/moddable/blob/public/documentation/network/ble/ble.md#esp32platform

Basically you need to set CONFIG_BT_ENABLED=y and one of CONFIG_GATTC_ENABLE/CONFIG_GATTS_ENABLE, depending on whether or not your BLE app implements the client or server role.

After editing the sdkconfig file, you might also need to ensure that the app is completely rebuilt clean. Delete the $MODDABLE/build/tmp/esp32/debug/ directory before running mcconfig. For example, if you are building the ble/advertiser app:

(edit the sdkconfig file options)
rm -rf $MODDABLE/build/tmp/esp32/debug/advertiser
cd $MODDABLE/examples/network/ble/advertiser
mcconfig -d -m -p esp32

We are hoping to simplify the sdkconfig steps in a future release.

Brian

I had already done the sdkconfig modification part before I tried the first time,
My git diff to the project just have bt enabled, as gatt server is enabled as default:

diogoviannaaraujo@Diogos-MBP:~/Git/moddable/examples/network/ble/heart-rate-server$ git diff
diff --git a/build/devices/esp32/xsProj/sdkconfig b/build/devices/esp32/xsProj/sdkconfig

But I still keep getting the same error, I've downloaded and recloned again idf, toolchain and moddable but seem to have no effect. Tried to remove build temp as you asked but keep getting in the same problem

Ive tried to verbose the mcconfig and it says its including the bt component from the idf, here is the end of output of mcconfig with verbose on:

Is it possible to be a idf version problem? im trying with latest master, should I be trying with one of the releases? last night I remember trying with one of the releases but I was too tired and dont remember if it was 3.0 or 3.1.. -__-

Im considering building a virtual machine to test on a clean macOS. Would it build on a raspberry pi? I could try there too

Hello -

Please add "#define CONFIG_BT_ENABLED 1" to the top of $MODDABLE/build/devices/esp32/sdkconfig.h and try building again. Let me know how that goes.

We are working on simplifying this part of the ESP32 build. Thank you for your patience.

Regards,
Brian

Hey, that worked!
And thank you for ur amazing work!

Got curious on where things did not work between the sdkconfig and the sdkconfig.h
Hope in the future I could be the one helping simplify this config part of the build

Glad to hear you are up and running Moddable BLE apps on ESP32. We appreciate your patience and offer to help!
