I would gladly do the same project but with ESP32 or raspberry – publisch it on a webpage
Specialy the graphs ar awsome (This graph is made with Nodered, InfluxDb and Grafana.)
With another sensor, the MSM261S4030H0 MEMS microphone

Hi.
I’m sorry, but I didn’t understand what was exactly your question? What is exacty your doubt? Can you be a little more specific?
That board is also an ESP 32 board, so the code they provide should be compatible with a “regular” ESP32 board as long as you adjust the connections of the sensors and OLED display.
Regards,
Sara

Dear Sara,
I’ve studiet the github file again.
I like the project very much but i want to run it on a esp32 wroom 32 (no Lora). Output if possible on a website.
Is this possible with some adjustments to this sketch ?
I get as far as this :
10:35:43.498 -> ets Jun 8 2016 00:22:57
10:35:43.498 ->
10:35:43.498 -> rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)

10:35:43.779 -> Task0 running on core 0

10:35:43.779 -> C:\Users\Guy\Documents\Arduino\libraries\MCCI_LoRaWAN_LMIC_library\src\lmic\oslmic.c:53
I know everything (board and sensor) is working because the sensor runs nicely on : https://github.com/ikostoski/esp32-i2s-slm
In lorasoundkit -> soundcensor.cpp i adjusted pins 18 and 23 (switching 18 and 23 did’nd make a change)
// define IO pins Sparkfun for I2S for MEMS microphone
const i2s_pin_config_t pin_config = {
.bck_io_num = 23, //(used to be 18)
.ws_io_num = 18,//(used to be 23)
.data_out_num = -1,
.data_in_num = 19
when i verify the sketch i get
C:\Users\Guy\Documents\Arduino\libraries\MCCI_LoRaWAN_LMIC_library\src\hal\getpinmap_thisboard.cpp:71:72: note: #pragma message: Board not supported — use an explicit pinmap
#pragma message(“Board not supported — use an explicit pinmap”)
Can you give me some advice please?

Hi.
It seems that some library that is being used is not compatible with your board, specifically the MCCI_LoRaWAN_LMIC_library. I’m not familiar with that library.
I think you should try to contact the developer of that project because he is familiar with the project and he’ll be able to help you better than I can.
Regards,
Sara
