So the only way is using the ESP as master, sending an inquiry to the slave (an Arduino Nano in my case) and waiting for its response.pythoncoder wrote: ↑Mon Apr 05, 2021 8:54 amUsing slave mode is quite difficult because of the way it is implemented. The slave has to be waiting on a transfer before the master will get a response. This doc describes the issue. What is needed is an asynchronous slave mode. It is possible that threading could be used to achieve this, but there is a question-mark over performance and I haven't tried it.
The Loboris port is abandonware. It is based on a long-superseded version of firmware and is effectively unsupported.
I'll go so.
Thanks to everybody for help!
