Do you have Disabled Login shell to be accessible over serial and Enabled Serial port hardware?
Please mention the status of LEDs of the Shield.
Thanks for the response. I updated my config with raspi-conf
. Unfortunately, I'm still seeing the same error.
Here's a picture of the LEDs on the hat...
Hey, Seems your module is not powered up. Could you please use official RPi power supply (5V 2.5A)?
Could you please manually power up the module pressing the POWER KEY? Once the module is powered up, you may see the STATUS LED turned ON and NETLIGHT LED BLINKING.
If it doesn't solve, Please try sending AT commands vis ttyS0 using minicom.
Thanks for the suggestions. Ok, I've
NETLIGHT
flashesSTATUS
LED is brighter redAT
does not show any response in either minicom
or socat
using sudo minicom /dev/ttyS0
and sudo socat - /dev/ttyS0
.
Any other ideas?
Also, is it possible to have this power up when the Pi powers up, or will I have to hit the PWRKEY
everytime?
Update: I was able to get this to work by connecting the USB jumper and using /dev/ttyUSB3
.
I'd like to keep that USB port free, so if you have any advice on getting /dev/ttyS0
working, I'd love to hear it.
Also, if you could tell me how to have this power up when the Pi boots, without having to use the PWRKEY
, that would be awesome.
try ttyAMA0
Hi, I got similar issue... it only works with mPCIE with those 4 ttyUSBx But when I tried to use the ttyS0, I have no way to get the ip address allocated.
Is it something related to the loaded Kernel modules? i.e. if attached the mPCIE -> USB serial driver loaded some modules that related to ip address module?
Any idea is appreciated!
