Finally I got it and even want to record video how apps written in B4i and B4A can link, read, and write data into some device even together at once
Android can handle BT Classic, BLE and MQTT where iOS BLE and MQTT.
For myDevice I use some another language where I can use two Internet link (Wizznet and ESP8266) for communicate with VPS and even crypted remote upgrade is possible.
This will be in on my wishlist because Im lovin BasicLanguage.
Thank you for your time to answear and confirm that this can be done...and not give me example
cause I learn a lot again.
