ESP32 PICO RFM69 (SPI) - communication problems arduino IDE

[LDavidFr]

Hello,
I use a esp32 pico with an RFM69.

Everything works fine except with the use of energy saving mode.

Solution 1:
Deel Sleep
The frames are sent but not processed by ESP32 (server).
I restart esp32 server to receive a correct frame. But the next trame are not processed.

Solution 2:
Light Sleep
Same code and lib, I use Light Sleep. It works.
But obligation to reduce energy consumption. So Deep Sleep.

SERVER

#include <RHReliableDatagram.h>
#include <RH_RF69.h>
#include <SPI.h>

#define CLIENT_ADDRESS 2
#define SERVER_ADDRESS 1
RH_RF69 driver(5, 26);
RHReliableDatagram manager(driver, SERVER_ADDRESS);

void setup()
{
  Serial.begin(9600);
  while (!Serial)
    ;
    delay(10);
    if (!manager.init())
    Serial.println("init failed");
    delay(10);
}

uint8_t data[] = "And hello back to you";
uint8_t buf[RH_RF69_MAX_MESSAGE_LEN];

void loop()
{
  manager.temperatureRead();
  if (manager.available())
  {
    uint8_t len = sizeof(buf);
    uint8_t from;
    if (manager.recvfromAck(buf, &len, &from))
    {
      Serial.print("got request from : 0x");
      Serial.print(from, HEX);
      Serial.print(": ");
      Serial.println((char*)buf);
     
      if (!manager.sendtoWait(data, sizeof(data), from)){
        Serial.println("sendtoWait failed");
    }else{
    }
    }
  }
}

CLIENT DEEP SLEEP After reboot SERVER, first trame is good (receive and ack) and next trame KO

#include <RHReliableDatagram.h>
#include <RH_RF69.h>
#include <SPI.h>

RTC_DATA_ATTR  uint8_t data[] = "Hello World!";
RTC_DATA_ATTR  uint8_t buf[RH_RF69_MAX_MESSAGE_LEN];
RTC_DATA_ATTR  uint8_t len = sizeof(buf);
RTC_DATA_ATTR  uint8_t from;  

void setup()
{
RH_RF69 driver(5, 13);
RHReliableDatagram manager(driver, 2);
Serial.begin(9600);
  if (!manager.init())
      if (!manager.init())
    Serial.println("init failed");
    Serial.println("Sending to rf69_reliable_datagram_server");
   
  if (manager.sendtoWait(data, sizeof(data), 1))
  {
    if (manager.recvfromAckTimeout(buf, &len, 2000, &from))
    {
      Serial.print("got reply from : 0x");
      Serial.print(from, HEX);
      Serial.print(": ");
      Serial.println((char*)buf);
    }
    else
    {
      Serial.println("No reply, is rf69_reliable_datagram_server running?");
    }
  }
  else
    Serial.println("sendtoWait failed");
    Serial.println("sendtoWait test");
    delay(500);
    esp_sleep_enable_timer_wakeup(5 * 100000);
    esp_deep_sleep_start();
}

void loop()
{
}

CLIENT LIGHT SLEEP Good for all trame (receive and ACK) but consumption is not ideal

#include <RHReliableDatagram.h>
#include <RH_RF69.h>
#include <SPI.h>

RTC_DATA_ATTR  uint8_t data[] = "Hello World!";
RTC_DATA_ATTR  uint8_t buf[RH_RF69_MAX_MESSAGE_LEN];
RTC_DATA_ATTR  uint8_t len = sizeof(buf);
RTC_DATA_ATTR  uint8_t from;  
RH_RF69 driver(5, 13);
RHReliableDatagram manager(driver, 2);

void setup()
{
Serial.begin(9600);
}

void loop()
{
  if (!manager.init())
      if (!manager.init())
    Serial.println("init failed");
    Serial.println("Sending to rf69_reliable_datagram_server");
   
  if (manager.sendtoWait(data, sizeof(data), 1))
  {
    if (manager.recvfromAckTimeout(buf, &len, 2000, &from))
    {
      Serial.print("got reply from : 0x");
      Serial.print(from, HEX);
      Serial.print(": ");
      Serial.println((char*)buf);
    }
    else
    {
      Serial.println("No reply, is rf69_reliable_datagram_server running?");
    }
  }
  else
    Serial.println("sendtoWait failed");
    Serial.println("sendtoWait test");
    esp_sleep_enable_timer_wakeup(5000000);
    esp_light_sleep_start();
}

RFM95 is same ... :/

Humm if send new request when after :recv failed: the server accept trame. (deep_sleep)
