Returns
Status Codes

◆ startTransmit() [2/4]

int16_t PhysicalLayer::startTransmit

Interrupt-driven Arduino String transmit method. Unlike the standard transmit method, this one is non-blocking. Interrupt pin will be activated when transmission finishes.

Parameters
strAddress of Arduino String that will be transmitted.
addrNode address to transmit the packet to. Only used in FSK mode.
Returns
Status Codes

◆ startTransmit() [3/4]

int16_t RF69::startTransmit ( uint8_t *  data,
size_t  len,
uint8_t  addr = 0 
)
overridevirtual

Interrupt-driven binary transmit method. Overloads for string-based transmissions are implemented in PhysicalLayer.

Parameters
dataBinary data to be sent.
lenNumber of bytes to send.
addrAddress to send the data to. Will only be added if address filtering was enabled.
Returns
Status Codes

Implements PhysicalLayer.

◆ startTransmit() [4/4]

virtual int16_t PhysicalLayer::startTransmit

Interrupt-driven binary transmit method.

Parameters
dataBinary data that will be transmitted.
lenLength of binary data to transmit (in bytes).
addrNode address to transmit the packet to. Only used in FSK mode.
Returns
Status Codes
