My modbus slave fails to receive the first command. The master returns a response timeout. However, from second attempt, the commands start working correctly. Wondering if someone else has faced this issue, or if anyone has any idea of what might be wrong here?

Hi Forum! Having built a number of projects using the ESP32, we wanted a consistent, easy to use framework. Not keen on disrupting quality, size or performance, we decided to come up with a custom framework over the ESP-IDF covering most common use-cases of the ESP32 in a "building block" style libr...
