Ho installato okmap (eccezionale) sul mio tablet Samsung 500T (xe500T1c per l'esattezza) con sistema operativo Windows 8. Purtroppo non riesco a configurare il GNSS (sensore di geolocalizzazione) integrato della Broadcom. Nel menù Utilità-Preferenze, GPS e NMEA non mi fa selezionare la porta. Sto sbagliando qualcosa? Debbo configurarlo in altro modo o Okmap dovrebbe vederlo in automatico?? Ringrazio anticipatamente  |

Grazie per i complimenti!
La selezione del GPS non è automatica, è necessario indicare la porta nelle funzione Utilità Preferenze alla pagina NMEA (non GPS che serve a comunicare con vecchi GPS tramite protocollo proprietario e comunque per scambio dati e non per la localizzazione).
Ti devi assicurare però che il GPS essendo integrato possa essere visto tramite una porta seriale come farebbe un dispositivo bluetooth.
Inoltre dovresti verificare che il protocollo utilizzato sia NMEA. |

Tutto mi sembra tranne che NMEA. Di seguito allego caratteristiche per una tua cortese verifica. Grazie
BCM47511 Integrated Monolithic GNSS Receiver
Providing dual constellation support for GPS and GLONASS, the BCM47511 receiver offers faster signal searches, accurate real-time navigation and improved sensitivity in urban canyon environments, while using very low average power.
The BCM47511 is the latest generation of standalone, Global Navigation Satellite System (GNSS) solutions, adding GLONASS functionality while remaining pin-compatible to the popular BCM4751 GPS, so customers can quickly upgrade their products to include the benefits of GLONASS navigation support. The BCM47511 also supports the Space Based Augmentation (SBAS) and Quasi-Zenith Satellite System (QZSS) constellations to deliver the best possible navigation performance in any geography.
The BCM47511 provides an optimized standalone GNSS solution for smartphones, mobile handsets, personal digital assistants (PDAs), portable media players and portable navigation devices (PNDs).
Request Product Info to learn more about Broadcom products or contact a Manufacturer Representative in your area.
Features
The GNSS core of the BCM47511 uses a host-based system architecture that splits processing functions between the GNSS chip and the host system CPU, significantly decreasing system cost, while allowing customization or optimization of GPS/GLONASS/QZSS/SBAS navigation software algorithms on the host. This software is compatible with Broadcom's existing GPS solutions, the BCM4750 and BCM4751, enabling rapid adoption while accelerating time-to-market
The host-based architecture permits the GNSS software processing tasks to be divided among the chip and the host CPU, so that the BCM47511 performs most of the computationally intensive operations, leaving the host software to implement the final calculations that may be affected by carrier and platform specific requirements. As a result, processing demands on the host CPU are minimized and no real time requirements are imposed
The BCM47511 provides low power consumption and an ultra low power tracking mode
The BCM47511 also includes on-chip low drop-out (LDO) regulators to supply the GNSS TCXO and optional low noise amplifier (LNA), reducing overall bill-of-materials (BOM) cost
Broadcom provides GNSS Location Library software API and GNSS protocol client software that gives designers complete access to the BCM47511's advanced capabilities

Ho visto anche il link http://www.broadcom.com/products/GPS/GPS-Silicon-Solutions/BCM47511 ma sinceramente non si capisce se NMEA è supportato da questo modello oppure no.
Forse ti conviene scrivere una email al produttore per capire qualcosa in più.
L'unico requirement per OkMap è una porta seriale su cui leggere il protocollo NMEA.
