BT TWS Earphones on the market have a touch-interface on the outside which is used for power on/off, pairing and all other interfaces (play/pause/next/etc.). We want a BT TWS Earphone that has a separate button for power on/off and pairing and a separate button for all other UI (play/pause/next/etc.). Our goal, by separating the on/off/pairing from the main interface is to have a long-press back, ...
from the farm to table food need to be monitored (temperature/humidity/door/Geo Location) using sensors. we should collect the data using different networks such as LoRa, Sigfox, NBIoT, Zigbee. need to create reports, real time alarms should be sent using email, sms, push notifications . I have attached interface of software now I am using.

I am using the esp8266 module connected to an Arduino. I am opening sending a simple GET request directly to my server, but it is requiring 5 seconds to fetch 900 bytes with a fast-connection. It takes only 50ms to ping the server, so the overhead must be elsewhere. I'm looking to lower this as much as possible, and I'm only looking for consultation -- not code implementation.
Looking for a development company / individual who can help build magnetic levitation system. There are several design specification available on the net which can help in the R&D process. It would be nice to have high quality components built in India, rather than imported from China. Let me know what you think and whether you can build / develop this for me.
