+LESRVDATA GATT Server Data Exchange
AT syntax: AT+LESRVDATA=<channel>,<hexdata>
Channels are created during GATT server definition using the AT+LEATTRIB command. After AT+LEATTRIB=complete, the GATT server is ready to be used.
All data for defined characteristics is sent over the corresponding channel. If a characteristic has a length of 4, 4 bytes of data has to be sent. The only exception is a defined length of 0, which means a variable length characteristic. All data sizes between 1 and 20 are allowed.
