Re: [web-bluetooth] Update Connection Interval (#528)

Hi, I believe the Central device can start a connection parameter update. See the specification bellow:

BLUETOOTH CORE SPECIFICATION Version 5.1 | Vol 6, Part B - 5.1.1  Connection Update procedure

If the master, the slave, or both do not support the Connection Parameters

Request Procedure, then the master shall send an

LL_CONNECTION_UPDATE_IND PDU (the slave shall not send this PDU)

while the slave shall use the L2CAP LE Signaling channel (see [Vol 3] Part A,

Section 4.20 and Section 4.21).

If a device supports the Connection Parameters Request Procedure but does

not know whether its peer does (because neither device has previously

attempted that procedure or performed a Feature Exchange Procedure), then it

shall initiate the Connection Parameters Request Procedure and, if the peer

responds with an LL_UNKNOWN_RSP PDU, by then using the method

described in the previous  paragraph.
