La carte Click Board™ BLE 10 est une carte complémentaire compacte qui fournit une connectivité BT/BLE pour toute application intégrée. Cette carte est équipée du PAN1780-AT (ENW-89854A3KF), un module Bluetooth® 5 Low Energy basé sur le contrôleur monopuce nRF52840 de Nordic de Panasonic. Les fonctionnalités Bluetooth® 5 permettent un débit de symboles plus élevé de 2 Mbps en utilisant le PHY LE 2M à haut débit, ce qui permet de diffuser des données beaucoup plus volumineuses dans des scénarios sans connexion. Le Nordic nRF52840 est livré avec un ensemble de commandes Bluetooth® AT.s LE BlueRadios nBlue™ intégré, un ARM® Cortex®-M4F, une mémoire Flash de 1 Mo et une RAM de 256 Ko offrant une grande flexibilité de conception, prenant également en charge la communication en champ proche (NFC) de type 2. Cette carte Click™ convient aux applications Bluetooth® à faible consommation d'énergie, aux environnements à fortes interférences, aux scénarios sans connexion et aux applications longue portée.
La carte Click Board™ BLE 10 est prise en charge par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette carte Click Board™ est un produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.
How Does The BLE 10 Click Board™Work?
The BLE 10 Click Board™ as its foundation uses the PAN1780-AT, a low-power Bluetooth® module that provides BLE connectivity for any embedded application from Panasonic. The PAN1780-AT is based on the Nordic nRF52840 single-chip controller with integrated BlueRadios nBlue™ Bluetooth AT.s LE Command Set. With its ARM® Cortex®-M4F, a 1MB Flash, and a 256kb RAM, the PAN1780-AT offers high design flexibility, alongside its new channel selection algorithm, which improves its performance in high interference environments.
The Bluetooth® 5 features an additionally higher symbol rate of 2Mbps using the high-speed LE 2M PHY or a significantly longer range using the LE Coded PHY. The output power of up to 8dBm and the high sensitivity of the nRF52840 combined with the LE Coded PHY make this module very attractive in long-range applications.
The PAN1780-AT communicates with MCU using the UART interface with commonly used UART RX, TX, and hardware flow control pins UART CTS and RTS (Clear to Send and Ready to Send) as its default communication protocol for exchanging AT commands. It operates at 115200bps by default configuration to transmit and exchange data with the host MCU. The PAN1780-AT uses a proprietary GATT profile developed by BlueRadios to stream data; it is not an official Bluetooth® profile. BlueRadios serial port implementation simplifies the user experience, allowing users to stream data similar to how the official Bluetooth® Serial Port Profile (SPP) works on BR/EDR devices. This Click board™ is also equipped with a USB type C connector, which allows the module to be powered and configured by a personal computer (PC).
In addition to these features, it also uses several other mikroBUS™ pins. A Reset button routed to the RST pin on the mikroBUS™ socket puts the module into a Reset state, while AN and IO3 pins routed to the AN and PWM pins on the mikroBUS™ socket represent analog signal monitor and GPIO signal which can be used as Sleep Mode toggle function. In addition, it has four orange LED indicators to indicate various functions such as Sleep mode activation, advertising, received data/commands, and successful module connections.
Two unpopulated headers can also be found on this Click board™, one of which is provided for the optional connection of an external NFC antenna (Type 2 Near Field Communication (NFC-A) for use in simplified pairing and payment solutions), while the second header represents three additional GPIO pins that carry a handful of additional functions whose description can be found in the attached datasheet.
The BLE 10 Click Board™ can be operated only with a 3.3V logic voltage level. Considering that the board can also be powered via USB, using the additional LDO, the TLV1117 achieves the required voltage of 3.3V required to power the module. An LDO and 3V3 mikroBUS™ power rail have protection in the form of diode MAX40200 to prevent any unwanted back voltage. The board must also perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
