Error trying to send transmit string of 16 characters #8

Closed targetarchitecture closed 3 years ago

Hi Gabriel, I'm using your library in my BBC Microbit & ESP32 board. I took your advice and have the BBC Microbit signalling a pin on the ESP32 to act as an interrupt. Everything is working well with sending text smaller than 16 characters in length. So my string "G,192.168.1.170" works fine. However if the string is longer such as "G1,192.168.1.170", then the following error occurs.

**sent: G1,192.168.1.170 assertion "heap != NULL && "free() target pointer is outside heap areas"" failed: file "/home/runner/work/esp32-arduino-lib-builder/esp32-arduino-lib-builder/esp-idf/components/heap/heap_caps.c", line 267, function: heap_caps_free abort() was called at PC 0x40103957 on core 1

Any thoughts on how to resolve this?

Thanks John in York (UK)

No problem, I'm glad you figured it out.

I had that in mind when I coded this library, but I couldn't find where I've written it. Are you sure I said this somewhere? 😅

LOL, I think it was in an old forum that you posted to before you wrote this library.
