Hello everyone, I have a problem and I can not get one. I have some ESP12 that I program easily with a stupendous programming board to which the module can be changed after programming. On the other hand, I have other seemingly similar modules of the Ai-Thinker that I'm not able to program them. I'm talking about programming with the IDE of arduino 1.8.5. error. espcomm_upload_mem filed. The good modules have no indicated vendor while the bad ones have AI-Thinker vendors. Can you help me?
Thank you
Luigi
