Hi,
currently I build some data-collecting system from sensors. It works in this way that uC collects some datas from various sensors and sends it through esp8266 to my program on pc-side. uC communicates with esp8266 through uart and esp8266 acts as wifi "adapter" for uC. On the pc-side works my program. This application on the one hand collects incoming datas from esp8266 (Synapse) and on the other hand acts also as http server (fpWeb) for presentation received data. Where is problem?
So actually it works, when I run this on pc (intel machine with Win7) - works without problems: connection is stabile, datas are collected without errors -test lasted for a few hours.
But when I run my application on RPi Stretch there it can be even after few minutes "host unreachable" or "connection timed out". My suspicions are antenna singnal range of RPi. The RPi doesn't act as AP. It is like another machine in my local net. Most likely I add to RPi external usb-antenna but maybe someone had similar issues with hardware (RPi) and knows what else to pay attention to?
Compilation made on Win7, Intel, Lazarus 2.0.10
