Pwede po b gamitin yung 4 wires ng data cable.yung parang sa pag flash sa 936?
Hindi ata kasi 3 lng need mo na sa UART.

Rx (receive)
Tx (transmit)
GND (ground)

kapag 4 kasi merong kasama na Vcc (Voltage-in) hindi need yun tsaka baka ma brick.

Tsaka yung USB-TTL parang may maliit na circuit board yun para basahin ng PC. Yung 936 kasi may USB port na kaya no need mag converter

ang alam ko compatible sila.
name lang naman ang pagkakaiba at yung gamit nilang firmware
Yes, may issue lang pagdating sa WIFI led kung nagsubok mag flash ng R281 firmware to R291, which is fixed in my private R291 test build.

BTW, napansin ko yun LTE modem mo runs SmartBro_CP_v003.1. Have you tried making this work with LTE fw version PLDT_CP_v002? How is the openline status in v003.1?

hindi ko na try i-openline ang hina kasi ng Globe samin at wala akong Globe na sim

gumagana ba yung sa LTE ng R291?
o ganyan din sa R281

Di ko na try tinkering with R291 LTE fw dahil nag convert ako agad to PLDT_CP_R281_v002 for permanent openline with ease of changing IMEI. Kaya sinusubukan ko paganahin ang connection with V002 under OpenWrt.

Pero maigi at napagana mo LTE connection with SmartBro_CP_R281_v003.1 under OpenWrt. Openline nalang kailangan diyan. I may try changing to this on my R291 and see how it goes.

sna ma gwan paraan sir😊😊para magka openwrt na sir r291/r281
 
balik mo muna sa stock firmware yan
login ka sa ssh
tapos mag lagay ka ng ganitong command sa /etc/rc.local
Code:
cat /dev/log_radio|grep "\[RIL1\|\[rild\|AT cmd">/tmp/rild

after niyan power off then power on
eh unplug dapat hindi reboot ha
login ka ulit sa ssh
eh run mo naman itong command
Code:
cat /tmp/rild|head -n 150
hanapin mo yung AT+CHECKATVALID=*
at kunin mo yan.
