Send and recieve data in one board ESP32CAM and SX1278 #59

Hi , Is there a difference between the settings of the receiver and the transmitter? How can I receive data from the receiver before sending the image in sender board? Is it correct to use the following sending and receiving codes? For example, in examples 240 and 241 :

In Receiver Board : if (setupLoRaDevice()) { sentOK = ARsendArray(Data_buf, Data_len, Code1, tempsize + 1); if(sentOK ) { arraylength = ARreceiveArray(PSRAMptr, sizeof(ARDTarraysize), ReceiveTimeoutmS); . . . / some code / . . } }

In Trasmitter Board : if (setupLoRaDevice()) { arraylength = ARreceiveArray(PSRAMptr, sizeof(ARDTarraysize), ReceiveTimeoutmS); if (arraylength ){ sentOK = ARsendArray(fb->buf, fb->len, filenamearray, tempsize + 1); . . . / some code / . . } }

For the camera programs the terms 'transmitter' and 'receiver' refer to the transmission and reception of the picture.

The 'transmitter' program sends a packet and then switches to receive mode to receive the acknowledgment. The 'receiver' program when it receives a packet switches to transmit mode to send the acknowledgment.

So both programs are aleady a working example of using a single ESP32CAM as a LoRa transmitter and receiver.

No issues with library.
