hello， frankfeng2020
能否帮我确认下BC28模组的联网的流程是否存在隐患
我们现在使用BC28JA-02-STD Revision:BC28JAR01A11
查询固件版本如下
SSB,V150R100C10B200SP1
SECURITY_A,V150R100C20B300SP7
PROTOCOL_A,V150R100C20B300SP7
APPLICATION_A,V150R100C20B300SP7
SECURITY_B,V150R100C20B300SP7
RADIO,Hi2115_RF1
现有的网络连接流程如下
ATI
AT+QREGSWT=1
AT+NRB
ATE0
AT+CGSN=1
AT+NCCID?
AT+CFUN=0
AT+NCSEARFCN
AT+CFUN=1
AT+CEREG=1
AT+NNMI=1
AT+NCDP=221.229.214.202,5683
AT+NSOCR=DGRAM,17,1,1
AT+NCONFIG=CELL_RESELECTION,TRUE
AT+NCONFIG=CR_0859_SI_AVOID,TRUE
AT+NCONFIG=CR_0354_0338_SCRAMBLING,TRUE
AT+NCONFIG=AUTOCONNECT,TRUE
AT+CGATT=1
AT+CEREG?
AT+CCLK?
AT+NUESTATS=CELL
Hi Luo
建议参考以下推荐流程，仅代表个人意见。
ATI
AT+QREGSWT=1
AT+NCDP=221.229.214.202,5683
AT+NCONFIG=AUTOCONNECT,TRUE
AT+NRB
AT（返回OK表示开机成功）
ATE0
AT+CGSN=1
AT+NCCID?
AT+CEREG=1
AT+NNMI=1
AT+CEREG?（重复查询，直到返回0，1或0，5后继续下一步，否则走异常处理流程）
AT+CGPADDR
AT+CCLK?
AT+NUESTATS=CELL
AT+NSOCR=DGRAM,17,1,1
异常处理流程：
AT+CFUN=0
AT+NCSEARFCN
AT+CFUN=1
AT+NRB
hi，abner，
1、这个参考流程有相关文档吗？
2、这个流程与我贴上去的流程的区别主要原因是什么
3、如果方便的话，能否加个微信，直接咨询一下，我的微信号zbhjlsd

In addition to environmental factors in choosing spacecraft materials, factors like weight, mass, gravity and energy usage must also be considered. Much like conventional aircraft, spacefaring vehicles must maintain a weight balance in order to safely achieve lift and maintain flight.
While orbiting, the mass of a spacecraft can affect its ability to use thrust and maintain a navigational vector. Because weight and mass are often correlated in design, both factors must be included in material choice for spacecraft.
