3Gband设置在代码里什么位置可以看到，比如Band1和8。我在Modem源码里看到的.mak文件里也只是
BAND_SUPPORT = QUAD
# Description:
# Described the support band of RF
# Option Values:
# DUAL900: Support 900/1800
# EGSM900: Support 900
# RGSM900: Support 900
# DUAL850: Support 850/1800/1900
# QUAD: Support 850/900/1800/1900
# PGSM900: Support 900
# DCS1800: Support 1800
# PCS1900: Support 1900
# GSM850: Support 850
# GSM480: Support 480
# GSM450: Support 450
# TRIPLE: Support 900/1800/1900
是这个地方吗
BAND_SUPPORT = QUAD

是这个地方吗
ul1d_custom_rf.h
这里面自己配置。
我这只有TD的源码
是custom\modem\tl1_rf\CUSTOM_MT6168RF_UMTS_TDD_RF9810\tl1d_custom_rf.h吗
#ifdef __UMTS_TDD128_BAND_E__
#define E_EN 1 //0 BAND_E disable 1: BAND_E enable
#else
#ifdef MT6589 //MT6589 always use VC1-3
#define E_EN 1 //0 BAND_E disable 1: BAND_E enable
#else
#define E_EN 0 //0 BAND_E disable 1: BAND_E enable
#endif
#endif
哪你的代码不支持WCDMA。
编译好的modem看不出来配的是多少吧 只能看源码吧?
WCDMA 要ul1d_custom_RF里面改
感謝分享，快來看看。
