Finally! A new release with something more than a bugfix or some minor additions!

I'm excited to present this release properly after the unfortunate Arduino Library Manager debacle 🎉.

This was a complete overhaul of the codebase, every file as been touched up and some completely re-designed, removed, added, or changed significantly. This required A LOT of changes, many will break your current application code, but don't worry, it will be much better!

This release has so much in it!

Highlights

  • Reduced the code size by over 40KB.
  • Significant reduction in memory use.
  • Huge performance boost.
  • Asynchronous client connect, MTU exchange, and secure connection options to speed up the connecting process.
  • Asynchronous passkey entry/confirmation so the client/server can have time to properly display/enter the passkey before action is performed.
  • Scan restart option to clear the duplicate cache so the same devices will be found again.
  • New scan callbacks class with extra functions that will get called on first discovery, before and scan response data is received.
  • Ability to update advertised data while advertising.
  • Improved support for dynamically changing services/characteristics/descriptors.
  • Simplified code for easier maintenance and understanding for contributors.

Full Changelog

Breaking changes

  • All connection oriented callbacks now receive a reference to NimBLEConnInfo, the ble_gap_conn_desc has also been replace with NimBLEConnInfo in the functions that received it.
  • All functions that take a time input parameter now expect the value to be in milliseconds instead of seconds.
  • Removed Eddystone URL as it has been shutdown by google since 2021.
  • NimBLESecurity class removed.
  • NimBLEDevice Ignore list functions removed.
  • NimBLEDevice::startSecurity now returns a bool, true on success, instead of an int to be consistent with the rest of the library.
  • NimBLEDevice::getInitialized renamed to NimBLEDevice::isInitialized.
  • NimBLEDevice::setPower no longer takes the esp_power_level_t and esp_ble_power_type_t, instead only an integer value in dbm units is accepted.
  • NimBLEDevice::setOwnAddrType no longer takes a bool nrpa parameter.
  • NimBLEDevice::getClientListSize replaced with NimBLEDevice::getCreatedClientCount.
  • NimBLEDevice::getClientList was removed.
  • NimBLEServer::disconnect now returns bool, true = success, instead of int to be consistent with the rest of the library.
  • NimBLEServerCallbacks::onMTUChanged renamed to NimBLEServerCallbacks::onMTUChange to be consistent with the client callback.
  • NimBLEServer::getPeerIDInfo renamed to NimBLEServer::getPeerInfoByHandle to better describe it's use.
  • NimBLEServerCallbacks::onPassKeyRequest has been replaced with NimBLEServer::onPassKeyDisplay which should display the pairing pin that the client is expected to send.
  • NimBLEServerCallbacks::onAuthenticationComplete now takes a NimBLEConnInfo& parameter.
  • NimBLEClient::getServices now returns a const reference to std::vector<NimBLERemoteService*> instead of a pointer to the internal vector.

  • NimBLEClientCallbacks::onPassKeyRequest has been changed to NimBLEClientCallbacks::onPassKeyEntry which takes a NimBLEConnInfo& parameter and does not return a value. Instead or returning a value this callback should prompt a user to enter a pin number which is sent later via NimBLEDevice::injectPassKey.
  • NimBLEClientCallbacks::onConfirmPIN renamed to NimBLEClientCallbacks::onConfirmPasskey and no longer returns a value and now takes a NimBLEConnInfo& parameter. This should be used to prompt a user to confirm the pin on the display (YES/NO) after which the response should be sent with NimBLEDevice::injectConfirmPasskey.
  • NimBLEAdvertising::setMinPreferred and NimBLEAdvertising::setMaxPreferred have been removed, use NimBLEAdvertising::setPreferredParams instead.
  • Advertising the name and TX power of the device will no longer happen by default and should be set manually by the application.
