  @gmnvh I reccomend to look in to "volos" projects on YT

  I worked for weeks on an enhancement of an Arduino sketch that shows time data of seven different timezones in the world. At intervals the RTC is updated with a datetime stamp from an SNTP service server.
  The past two weeks I was adding the functionality to send some data, like time sync time_t value to a Google Sheets spreadsheet. This all works OK.
  The sketch ran a whole night, every 15 minutes sending data to a Google Apps Scripts script that adds the data to the spreadsheet.
  In the sketch I have built the possibility to switch the display off (go to sleep) by using the command: "M5.Display.sleep()" and switch the display
  on (awake) by using the command: "M5.Display.wakeup()". The switching off or switching on is done by holding an RFID card in front of the display. The sketch also has the possibility to switch the display on or off by touching the display (it is one or the other option. For now I use the RFID tag option). I used the Arduino IDE v2.3.3. for MS Windows 11. The Arduino IDE compile and build reports :

  Sketch uses 1190657 bytes (90%) of program storage space. Maximum is 1310720 bytes. Global variables use 53384 bytes (16%) of dynamic memory, leaving 274296 bytes for local variables. Maximum is 327680 bytes. esptool.py v4.5.1 Serial port COM6 Connecting... Chip is ESP32-S3 (revision v0.2) Features: WiFi, BLE Crystal is 40MHz [...] Wrote 1191024 bytes (721826 compressed) at 0x00010000 in 8.6 seconds (effective 1113.8 kbit/s)...

  During the execution of the sketch calls to ESP.getFreeHeap(), result in values like: 265556 downto 264052.

  After the display goes black, the sketch continues to execute fine, sending at the preset intervals its data to the Google Sheets spreadsheet.

  Anyone that give me a clue to solve this abnormal behaviour?

  Any idea? Is it possible to use it with http get or MQTT commands?
  Any pointers?
  Thanks

  @felmue Thank you for the pointer! Looks like perhaps it's fixed for the Arduino implementation? It does not seem fixed for the ESP-IDF version quite yet. Your workaround combined with the pre_cb and post_cb callbacks worked! Here's a snippet/summary of what I did:

  #ifdef CONFIG_M5CORES3_SPI_CONFLICT_FIX #define M5CORES3_SPI_CONFIG_FIX_MISO_PIN 35 void sx127x_spi_pre_transfer_m5cores3_fix_callback(spi_transaction_t* t) { // before a SPI transaction is started, we need to change the driving direction // of the DC pin in the CoreS3 (the CoreS3 uses the MISO pin as the DC pin and // configures it as an output ping which conflicts with other SPI devices on the bus) // set gpio direction for MISO pin to input gpio_set_direction(M5CORES3_SPI_CONFIG_FIX_MISO_PIN, GPIO_MODE_INPUT); } void sx127x_spi_post_transfer_m5cores3_fix_callback(spi_transaction_t* t) { // undo pin direction change after SPI transaction is done // set gpio direction for MISO pin back to output gpio_set_direction(M5CORES3_SPI_CONFIG_FIX_MISO_PIN, GPIO_MODE_OUTPUT); } #endif sx127x_handle_t sx127x_init(const sx127x_modem_config_t* modem_config) { // ... // Configure SPI device spi_device_interface_config_t spi_dev_cfg = { .clock_speed_hz = 9000000, // 9MHz .mode = 0, .spics_io_num = modem_config->cs_gpio, .queue_size = 7, .flags = 0, #ifdef CONFIG_M5CORES3_SPI_CONFLICT_FIX .pre_cb = sx127x_spi_pre_transfer_m5cores3_fix_callback, .post_cb = sx127x_spi_post_transfer_m5cores3_fix_callback #endif }; ret = spi_bus_add_device(spi_host, &spi_dev_cfg, &device->spi); if (ret != ESP_OK) { ESP_LOGE(TAG, "Failed to add SPI device"); vSemaphoreDelete(device->spi_mutex); free(device); return NULL; } // ... }

  I can now use both the display and the sx1276 at the same time on the M5Stack CoreS3.

  Thanks again for your assistance!
