RE: "Enable Packet Data Protocol AT command" issue in "Configure nRF Connect SDK Project"

Hi!

The problem is still not fixed with NCS 1.1.1. It is caused by the context strings and applies also to PDN_AUTH_CMD.

To fix that, go to lte_link_control folder in ncs/nrf/drivers and edit Kconfig to add escape signs:

if LTE_PDP_CMD
config LTE_PDP_CONTEXT
	string "Packet Data Protocol Context"
	default "0,\\\"IPv4v6\\\",\\\"internet.apn\\\""
	help

...

if LTE_PDN_AUTH_CMD
config LTE_PDN_AUTH
	string "PDN connection authentication parameters"
	default "0,1,\\\"username\\\",\\\"password\\\""
	help

This solves the issue and allows to use those fields in configurator, but that will not work during the network setup 🙂

To use those fields, use directly source code:

#if defined(CONFIG_LTE_PDP_CMD)
static const char cgdcont[] = "AT+CGDCONT=1,\"IP\",\"internet\"";

In line 125 of lte_lc.c

Hi Ronan,

Thank you for your feedback. That looks like a bug in SES, I will report it internally so it will be fixed in the next revision.

Instead, you can set the configurations directly in the prj.conf file found in the application/samples folder which you are working in.

Please add the following:

CONFIG_LTE_PDP_CMD=y

CONFIG_LTE_PDP_CONTEXT="0,\"IPv4v6\",\"internet.apn\""

And change the APN to what you like.

Best Regards,

Martin L.
