Sensor crashing stack overflow on ESP8266 12F board

[machasm1]

Getting the error below when uploading code to ESP8266 12F board. ESP Decoder does not function under Arduino IDE 2.0 so struggling to find the root cause of the problem. Any ideas?

To be clear: Does the error occur after the ESP-NOW message was sent? What board definition are you compiling under?

Could you try it on this newer version and tell me if the error is still present?

[machasm1]

Hi Thanks for the quick response. It just keeps looping round that whole error message as described above. This is with the newest release that you pointed me to (23_01).

I am using the Arduino IDE 2 and the board is a NodeMCU 1.0 (ESP12E Module). Running on Windows 11 Getting a compilation error when trying to use the stable release version as shown

I'll check some things and get back to you soon. But in the meantime: make sure that you don't have two copies of FDRS in your 'libraries' folder. It looks like you installed the new version with a different folder name, but this will confuse Arduino. Delete "C:\Users\joe\Documents\Arduino\libraries\Farm-Data-Relay-System-main" and try again.

[machasm1]

Yeah already noticed the duplicate folder problem so took the main one out of the libraries folder. As as side note I am trying to run this on a D1 mini esp8266 if that makes any difference. Also same problem occurs when trying to run the LoRa sensor. Sketches 1_UART_Gateway, ESPNOW_Controller, ESPNOW_Repeater and ESPNOW_Stress_Test all ran ok. It would appear it is something to do with the sensors only?

[aviateur17]

For ESP-NOW sensor sketch, wonder if it's getting stuck in this loop: fdrs_node.h line 469:

while(esp_now_ack_flag == CRC_NULL){ delay(0); }

There is no yield() so if the loop does not return the controller watchdog timer will expire and reset the CPU. probably best to add a yield(); command there if there isn't one in the current branch.

So then the question is why no ack flag. I haven't spent much time going through the scenarios but do you have a ESP-NOW gateway configured and listening at address 2?

[aviateur17]

Also same problem occurs when trying to run the LoRa sensor.

Can you send the debug output for the LoRa sensor sketch?

[timmbogner]

Good save, Jeff! It looks like I was under the impression that delay(0) would also yield(), and maybe it does in ESP32.

I'm wondering if the LoRa issue isn't the same thing in a different spot.

[timmbogner]

@machasm1 Try the new branch again and let me know if ESP-NOW works better.

[machasm1]

WooHoo Well done guys. Problem solved and in double time too.

[timmbogner]

Big thanks to both of you!

On LoRa the issue is while (true); after RadioLib init fails. On ESP32 it just hangs, but on ESP8266 it crashes. There's probably a better way to do that.
