Na konferencji 38s3 przedstawiono referat dotycz\u0105cy przeprowadzenia in\u017cynierii wstecznej oprogramowania oraz systemu komend chip\u00f3w TI SimpleLink (CC13XX i CC26XX) z obs\u0142ug\u0105 BLE (Bluetooth Low Energy), co umo\u017cliwi\u0142o stworzenie odbiornika FM. Transmitter analogowy prawdopodobnie nie b\u0119dzie zrealizowany \u2014 chipy s\u0105 wy\u0142\u0105cznie cyfrowe. <\/p>\n

W uk\u0142adach zastosowano DSP, a g\u0142\u00f3wne rdzenie ARM Cortex zarz\u0105dzaj\u0105 rdzeniem radiowym (RF Core) Arm Cortex-M0, kt\u00f3ry zapewnia g\u0142\u00f3wnemu rdzeniowi ograniczony interfejs oparty na przesy\u0142aniu komunikat\u00f3w. Pami\u0119\u0107 rdzenia radiowego mo\u017cna modyfikowa\u0107 za pomoc\u0105 patchy, kt\u00f3re pozwalaj\u0105 na zmian\u0119 zachowa\u0144 radiowej podsystemu. Producent uk\u0142ad\u00f3w oferuje modu\u0142y wspieraj\u0105ce r\u00f3\u017cne protoko\u0142y bezprzewodowe, realizowane z wykorzystaniem dynamicznych bibliotek i patchy pami\u0119ci (podobnie jak te stosowane w uk\u0142adach Broadcom, kt\u00f3re obecnie s\u0105 w\u0142asno\u015bci\u0105 firmy Cypress). Z kolei rdze\u0144 radiowy zarz\u0105dza DSP o specyficznej architekturze. <\/p>\n

Autorzy referatu odtworzyli proprietarny format patchy RF i zademonstrowali, jak przygotowa\u0107 w\u0142asne patche do dodania wsparcia dla nowych protoko\u0142\u00f3w bezprzewodowych (np. zrealizowano odbiornik FM), zarz\u0105dzania podsystemem bezprzewodowym i wymiany oprogramowania. Narz\u0119dzia do tworzenia i wysy\u0142ania patchy, a tak\u017ce assembler dla systemu polece\u0144 u\u017cywanego w DSP, opublikowano na licencji MIT. Obecnie w repozytorium brakuje kodu \u017ar\u00f3d\u0142owego oprogramowania, realizuj\u0105cego analogowy odbiornik.
