Добрый день. Поделитесь рабочей конфигурацией на 800мгц.
Любой канал лишь бы была уже проверена в железе на 800.
Уже двое суток не встаю из за кампа. Попробовал несколько конфигураций пока безрезультатно.
Попаду домой выставлю схемку и инициализацию свою. Уже переехал с аппаратного SPI на програмный.
Благодарю.

Моя инициализация на 800 мгц. Взят с сети. Разарботал немецкий программист. Большенство ссылаются именно на этот код как самы рабочий 
Сейчас тестировал такой код. Програмный SPI. Вручную дёргаю ногами передача прием. Уже не знаю на что грешить.

Если еще надо могу поделится ! Скачал откудато пример - переделал за 1 час по stm32f103 - сразу заработало, но пока не пригодилось ! (правда особо глубоко невникл , но данные от одного к другому модулю передает без проблем). Кстати удивила дальность уверенного приема – очень прилично для такого модуля !
