@ -383,18 +383,23 @@ The security callback methods are now incorporated in the `NimBLEServerCallbacks
The callback methods are:
> `bool onConfirmPIN(uint32_t pin)`
> `bool onConfirmPIN(const NimBLEConnInfo& connInfo, uint32_t pin)`
Receives the pin when using numeric comparison authentication, `return true;` to accept.
Receives the pin when using numeric comparison authentication.
Call `NimBLEDevice::injectConfirmPIN(connInfo, true);` to accept or `NimBLEDevice::injectConfirmPIN(connInfo, false);` to reject.
<br/>
> `uint32_t onPassKeyRequest()`
> `void onPassKeyEntry(const NimBLEConnInfo& connInfo)`
For server callback; return the passkey expected from the client.
For client callback; return the passkey to send to the server.
Client callback; client should respond with the passkey (pin) by calling `NimBLEDevice::injectPassKey(connInfo, 123456);`
<br/>
> `void onAuthenticationComplete(NimBLEConnInfo& connInfo)`
> `uint32_t onPassKeyDisplay()`
Server callback; should return the passkey (pin) expected from the client.
<br/>
> `void onAuthenticationComplete(const NimBLEConnInfo& connInfo)`
Authentication complete, success or failed information is available from the `NimBLEConnInfo` methods.
