Our client wants to send data from our device to BLE gateway. The device has to act as beacon. If i use eddystone beacon format, how much data it is possible to transmit to BLE gateway?

Aukstkalnis commented 4 years ago

Never mind this. I just found out, that BLE packets are max 31 B size and we need to broadcast at least 100 bytes...

You can't "send data" over eddystone, you can only advertise up to 17 bytes of an URL address or a 16-byte UUID. If you want to transmit data over BLE you need to connect your peripheral device to a GATT server on your central device.
