Other Parts Discussed in Thread: SYSBIOS, CC1350
您好，請問我們正在整合RX和UART，主要是讓兩個裝置能UART用無線相互傳送顯示(uart輸入資料儲存於packet[2]，並轉換成INT再TX，RX則是在callback_packet[2]中 )，目前配合smartRF stdio 測試TX應該沒有問題
但RX遇到以下問題:
1.測試傳送"123456789"，如果在RX接收成功時執行UART_write第一個字大部分的時候都無法接收(我在RX callbaclk內有printf進行測試)。
2.目前使用RX endtime來關閉RX，因為先使用RX但如果需要TX時，無法將目前正在執行的RX關閉，需要等收到RX訊號後才會TX，不知道目前這個timeout關閉RX的方式是否正確或是標準
程式基本上都是參照RfpacketRX進行修改的，程式碼如下(這是在mainThread內使用task):
