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

[RonanB96]

Versions:

Segger Embedded Studio v418,

nRF SDK v1.0.0 tag

For the NB-IoT network I wish to connect to, I need to specify the APN, I can see through "Configure nRF Connect SDK Project" I can enable "Enable Packet Data Protocol AT command" which should then show a text box where I specify the APN. But when I enable the PDP AT command checkbox, I get a JavaScript Alert saying "Syntax Error: Unable to parse JSON string"

If I configure the project with this setting, the "Configure nRF Connect SDK Project" menu returns the same JavaScript Error when I open the window and the is no menu items.

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.

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\"";
