AT+COPS 與基地站相關的操作

列出所有的基地站

at+cops=?
+COPS: 
(1,"Chunghwa Telecom","Chunghwa","46692",7),
(2,"Chunghwa Telecom","Chunghwa","46692",2),
(1,"TWN APT","APT","46612",7),
(3,"TWN APT","APT","46605",7),
(3,"TW Mobile","TWM","46697",2),
(3,"T Star","T Star","46689",7),
(3,"TW Mobile","TWM","46697",7),
(3,"T Star","T Star","46689",2),
(1,"Far EasTone","FET","46601",2),
(3,"TWN APT","APT","46605",2),
(1,"Far EasTone","FET","46601",7),
,(0-4),(0-2)

回答的每一行的每一個item是:

(stat,long alphanumeric,short alphanumeric,numeric,AcT)

stat:

• 0: 未知
• 1: 可用
• 2: 目前使用中
• 3: 禁用

long/short aplhanumeric 就是 operator的名稱，全名和縮寫。
Act 就是基地站的技術

• 0 GSM
• 1 GSM Compact
• 2 UTRAN
• 3 GSM w/EGPRS
• 4 UTRAN w/HSDPA
• 5 UTRAN w/HSUPA
• 6 UTRAN w/HSDPA and HSUPA
• 7 E-UTRAN

所以上面的list 可以看出...目前用的是 Chunghwa, UTRAN (就是3G)

設定自動選擇基地站 at+cops=0:

at+cops=0
ok

CTZE: "+32",0,"2024/05/07,02:26:11"

+CTZE: "+32",0,"2024/05/07,02:42:37"

設玩好像重新開機，然後問目前的基地站是:

AT+COPS?
+COPS: 0,2,"46692",7

OK

手動選擇基地站要用at+cops=1:

at+cops=1,2,"46692",2
OK

+CTZE: "+32",0,"2024/05/07,02:54:36"

好像也會重開機?
1 代表 手動，後面的 2 是 format 用 numberic, 所以後面用 "46692" 也就是 Chunghwa Telecom 的 numberic 代表號，最後是基地站的技術 7 - E-UTRAN也就是 LTE.
