I was Compiling code for nodemcuesp8266 and i got this error

``C:\Users\abhij\Documents\Arduino\libraries\AzureIoTHub\src\iothub_client_ll_uploadtoblob.c:26:27: fatal error: internal/blob.h: No such file or directory

@ForgottenTale have you followed the steps properly https://github.com/Azure/azure-iot-arduino#esp8266

I also faced the same issue.

Actually i didn't. Later on after i did. After i entered -DDONT_USE_UPLOADTOBLOB -DUSE_BALTIMORE_CERT to the platform.txt like this build.extra_flags=-DESP8266 -DDONT_USE_UPLOADTOBLOB -DUSE_BALTIMORE_CERT, i compiled the code and got this error on the arduino IDE.

I also faced the same issue.

Am i getting this error cause i added the -DDONT_USE_UPLOADTOBLOB -DUSE_BALTIMORE_CERT to the platform.txt improperly ? Also i couldn't find tlsio_mbedtls.c is in the adapters folder but i couldn't understand where to look for tlsio_mbedtls.c to check if it is defined or not

[abhijith452]

After i restarted my pc. Its working.
