// 'DISABLE_AP'
|

// --> disabling AP is for teensy audio samplers.
|

// they need this to reduce noise from AP beacon signals.
|
||||
// but, then they cannot build-up net. by themselves.
|
||||
// we need who can do AP..

// ==> TODO! just prepare some 'dummy' postmans around. w/ AP activated.
|

//
|
||||
// 'DISABLE_I2C_REQ'
|
||||
// --> a quirk.. due to bi-directional I2C hardship.
|
||||
// ideally, we want to make this sampler node also speak.
|
||||
// but, I2C doesn't work. maybe middleware bug.. we later want to change to diff. proto.
|
||||
// for example, UART or so.
|
||||
// ==> BEWARE! yet, still we need to take off this.. for 'osc' node.

// 'SET_ROOT'
