Failed to get remote characteristic

Hi!

I am trying to talk to a plant monitor over BLE using ESP32. I am able to talk to it from Raspberry PI, using Bluepy (using handles, though). With NimBLE, while some characteristics are working fine, attempts to read others fail.

The code that connects, gets a value from one characteristic, then fails to get another is below, along with gatttool output:

#include "NimBLEDevice.h"

void setup() {
  Serial.begin(115200);
  Serial.println("Hello World!");
  BLEDevice::init("");
  BLEDevice::setPower(ESP_PWR_LVL_P7);

  BLEClient* floraClient = BLEDevice::createClient();
  BLERemoteService* floraService = nullptr;
  static BLEUUID serviceUUID("00001204-0000-1000-8000-00805f9b34fb");
  static BLEUUID uuid_version_battery("00001a02-0000-1000-8000-00805f9b34fb");
  static BLEUUID uuid_sensor_data("00001a01-0000-1000-8000-00805f9b34fb");
  static BLEUUID uuid_write_mode("00001a00-0000-1000-8000-00805f9b34fb");
  static BLEUUID uuid_timer("00001a12-0000-1000-8000-00805f9b34fb");
  static BLEUUID uuid_history_control("00001a10-0000-1000-8000-00805f9b34fb");
  static BLEUUID uuid_history_read("00001a11-0000-1000-8000-00805f9b34fb");
  BLERemoteCharacteristic* floraCharacteristic;

  //  BLEAddress floraAddress("c4:7c:8d:66:34:90"); // rose
  BLEAddress floraAddress("c4:7c:8d:63:c7:ea"); // bamble Espressi 0c:b8:15 - 77:1a:2a
  if (!floraClient->connect(floraAddress)) {
    Serial.println("- Connection failed, skipping");
    return;
  }

  if(!floraClient->discoverAttributes()){
    Serial.println("- attributes failed to get discovered");
    return;
  }else{
    Serial.println("- attributes discovered");
  }

  floraService = floraClient->getService(serviceUUID);
  if (floraService == nullptr) {
    Serial.println("- Failed to find data service");
    return;
  }else {
    Serial.println("- Found data service");
  }

  floraCharacteristic = nullptr;
  std::string value;
  // get the device battery characteristic -------------
  Serial.println("- Access battery characteristic from device");
  floraCharacteristic = floraService->getCharacteristic(uuid_version_battery);
  if (floraCharacteristic == nullptr) {
    Serial.println("-- Failed, skipping battery level");
    return;
  }

  // read characteristic value
  Serial.println("- Read value from characteristic");
  value = floraCharacteristic->readValue();
  const char *val2 = value.c_str();
  int battery = val2[0];
  Serial.print("-- Battery: ");
  Serial.println(battery);

  Serial.println("- get history control");
  floraCharacteristic = nullptr;
  floraCharacteristic = floraService->getCharacteristic(uuid_history_control);
  if (floraCharacteristic == nullptr) {
    Serial.println("-- Failed, skipping device");
    return;
  }else{
    Serial.println("-- Got the characteristic");
  }
}

void loop() {
}

output:

18:46:40.861 -> Hello World!
18:46:46.266 -> - attributes discovered

Could you enable logging with the level set to debug and post the log of this please?
