Description of defect

From https://github.com/ARMmbed/mbed-os-example-ble/issues/355#issuecomment-805578819

They do not compile on GCC 9.3.1. I tried using the online compiler with the periodic advertisement example, while it compiles i can't get the Bluetooth to work properly (on a ST WB55).

Target(s) affected by this defect ?

ST WB55

Toolchain(s) (name and version) displaying this defect ?

GCC

How is this defect reproduced ?

Try to compile the application with GCC 9.6.3. It does not compile. Try to execute the application compiled with the online compiler: It doesn't work.

@pan- Did you try on your side...?

jeromecoutant commented 3 years ago

Then as explained in https://github.com/ARMmbed/mbed-os-example-ble/tree/master/BLE_PeriodicAdvertising Devices must support extended advertising and periodic advertising (Bluetooth version 5+).

Thank you @jeromecoutant.

@Arjun765 we now have a handy new example: https://github.com/ARMmbed/mbed-os-example-ble/tree/development/BLE_SupportedFeatures which lists the available features.

@jeromecoutant I opened the issue to keep track of it rather than it being buried in another issue. It is expected extended advertising won't work on WB55. If a user face the same issue it can search for this one and try out the BLE_SupportedFeatures example. Compilation is fine though.

Arjun765 commented 3 years ago

BLE_SupportedFeatures works on a WB55. Tried the BLE_Advertising on a nrf52840, while i can see it advertising as "BATTERY" i can't connect to it. The nrf mobile app says "Error 133, GATT error"

paul-szczepanek-arm commented 3 years ago

That is correct. It is advertising with non-connectable advertising. You can connect to BLE_GattServer_CharacteristicWrite or BLE_GattServer_AddService for example.
