Sending more than 20 bytes in write characteristics

[Newbie]

HI,

I am using sdk 12.2.2 and nrf52. I have write characteristics in my beacon but I can only send 20 bytes in one write cycle. How can I send more than 20 bytes?

No, you cannot. That is the limitation of BLE 4.  You'll need to breakdown your transmission to multiple send of 20 bytes.  With BLE5 you can send bigger packet.
