Hello I’m using Qnavigator / QCOM to test MQTT example before to programming into a mcu.
My trouble is around to upload certificates like AmazonCA1.pem, for this purpose as documentation said:
AT+QFUPL="ca.pem",1188
quectel response “CONNECT”

option 1:
QCOM use by default a char test I’ m not sure if \n will work because it will be interpreted as two chars not like EOL (\n) and if you can not put enter into input box…
no way…
option 2:
QCOM has another option to send as Hex:
you need check (via checkbox) Hex option and also need uncheck Enteroption (via checbox)
first step is convert this file in hex via linux terminal:
xxd -plain AmazonRootCA1.pem > AmazonRootCA1.pem.hex
# after we need count number of
wc -m AmazonRootCA1.pem.hex
the length to send is 2376 (1188*2=2376 a byte is two chars in hex) the hex to send is:
