### ADDITIONAL CONTEXT
Trying to get a response back from the SIM800L module. Module Rx is hooked to GPIO1 (Tx) and Tx to Rx. My script is as follows:

D 170 SB=4096 IP=192.168.4.1 command="" res=0 rstr="" substr="" lat=0 lon=0 spd=0 B res=so(1 3 9600 8N1 170) T lat=GPS#lat lon=GPS#lon F res=sa() if (res>100) { rstr=sr() } S print %substr% %rstr% if (upsecs%10==0) { print %5lat% %5lon% %res% command="" command="AT+CCID" ;=>serialsend2 %command% sw(%command%) }

Module is powered on and registered on cell network. What am I doing wrong with serial commands?

(Please, remember to close the issue when the problem has been addressed)

you can not mix scripting serial cmd with tasmota serial send.

the cmd sw() is a script cmd and does not recognize %% but a string

sw(command)
