STM32CubeMonitor-RF 2.19.0 not sending ACI_GATT_CONFIRM_INDICATION after receiving indication

[connoisseur_de_mimi]

I have a characteristic that supports write and indicate. A command is written to the char, the server responds by indicating the characteristic to the client. 

I'm using Stm32CubeMonitor-RF 2.19.0 to test the server, but indications always cause a ACI_GATT_PROC_TIMEOUT_EVENT because STM32CubeMonitor-RF does not issue a ACI_GATT_CONFIRM_INDICATION after an indication is received. 

log file attached.

[Richard.Chvr]

Thank you for the log. 

Sound like being a bug in CubeMonitor-RF, because ACI_GATT_PROC_COMPLETE_EVENT happens, the tool considers the command is finished and does not wait for any further event and ignores the ACI_GATT_INDICATION_EVENT. 

Issue have been reported to dev team.
