Zewelor compile 了 omapzoom 的 fmapp, 可用來測試 fm radio 的功能.

目前我們在 Milestone 上試了所得的 RSSI level 都是接近 0 的. 想試試在 xt701 上會有甚麼值才是正常.

可以試試在你的 xt701 上跑跑 fmapp 嗎?

現在 Zewelor 正在修改 fmapp 讓幫忙的大大用最簡單的方式, 而又不需要改變閣下手機的 ROM. (因 omapzoom 預設是把 socket 寫在 /etc/misc/hcid/ti_....... 而 bts 則在 /etc/firmware 下.

使用 fmapp 的截圖(我懶懶的使用了 android terminal emulator, 當然可以用 adb):

抱歉這麼遲才貼~

x0.nu.mu/~omen/fmapp

這是根據 http://git.omapzoom.org/?p=platform/hardware/ti/omap3.git;a=tree;f=fmradio;hb=HEAD
這裡改動到能編譯的版本.

/etc/firmware/fm*.bts 已改由 /etc/ 中讀取, 應和 xt701 一樣.

socket file 已改由 /data/misc/hcid/ti.. 至 /tmp, 應該不會在手機中建立資料.

由於 fmapp 會在 cwd 建立兩個 log files(fmapp.log 和 fmstack.log), 最好把 fmapp 放到 /tmp, cd 到 /tmp 執行.

這樣設置:

adb push fmapp /tmp
adb shell chmod 755 /tmp/fmapp

執行步驟:

1. 先關 bluetooth
2. 開啟 bluetooth
3. adb shell
cd /tmp
./fmapp

或參看上圖下達指令, 感激!!

另, 知不知道 xt701 有沒有 rfkill1 的?

這樣去檢視:

$ ls /sys/class/rfkill/
rfkill0

^^^^^^ 在 Milestone 上的結果

非常感激 gmtmkm 大大!!!!!

實驗結果和預期配合, 現得知正常的確認頻道的 RSSI level 是大概 18, 就算在不確認頻道也有 8.

注意在測試時 fmapp 要正常退出 power off.

如果出現 connection timed out 或 error, 可試試重啟籃芽.

現在的 FM 研究, 似乎接近尾聲了......剩下來的便要看看接受方便的線路有沒有希望.
