Detailed Description

This dbt_repeater00 C++ repeater example implementing a GATT repeater, i.e.

forwarding client requests to a GATT server and passing the results back.

The repeater can be used in between an existing Bluetooth LE client and server, acting as a forwarder and to analyze the GATT client/server protocol.

dbt_repeater00 Invocation Examples:

Using scripts/run-dbt_repeater00.sh from dist directory:

Connection to server TAIDOC TD1107 using adapter DC:FB:48:00:90:19; Serving client as TAIDOC TD1108 using adapter 00:1A:7D:DA:71:03; Using ENC_ONLY (JUST_WORKS) encryption.
../scripts/run-dbt_repeater00.sh -adapterToServer DC:FB:48:00:90:19 -adapterToClient 00:1A:7D:DA:71:03 -server 'TAIDOC TD1107' -nameToClient 'TAIDOC TD1108' -seclevelToServer 'TAIDOC TD1107' 2 -seclevelToClient 2 -quiet
