Hello, I'm trying to send long packets (> 20 bytes), so I added a custom service with characteristic supporting notification and indication with a size = 40 bytes.
After connection established, I send a LL_LENGTH negotiation to update the TxOctets to 40 bytes (using hci_le_set_data_length api)
The remote master configured the characteristic to notify.
I tried then to send a notification of 40 bytes ... only 20 bytes were sent.
I also tested to use hci_le_write_suggested_default_data_length api before the connection establishment, the negotiation was done successfully, but unable to send packets > 20 bytes
what is missing to be able to send packets > 20 bytes ?
