Hello , im having the same issue , but my client work and ouput :
No reply, is rf95_server running?Sending to rf95_server

but my server just output
rf95 server test`
but no information from my client what did i do wrong ?

Client script :

```// rf95_client.pde
// -- mode: C++ --
// Example sketch showing how to create a simple messageing client
// with the RH_RF95 class. RH_RF95 class does not provide for addressing or
// reliability, so you should only use RH_RF95 if you do not need the higher
// level messaging abilities.
// It is designed to work with the other example rf95_server
// Tested with Anarduino MiniWirelessLoRa

#include <RH_RF95.h>

// If you are using RFM95/96/97/98 modules which uses the PA_BOOST transmitter pin, then

rf95.setFrequency(868.0);

}

void loop() {
ShowSerial.println(“Sending to rf95_server”);
// Send a message to rf95_server

rf95.waitPacketSent();

uint8_t buf[RH_RF95_MAX_MESSAGE_LEN];
uint8_t len = sizeof(buf);

if (rf95.waitAvailableTimeout(3000)) {
    // Should be a reply message for us now
    if (rf95.recv(buf, &len)) {
        ShowSerial.print("got reply: ");
