Does SLM application support IPV6

[praveenpalaparthi]

Hi Nordic,

Does SLM application support IPV6, if yes could you please point us to the AT command set which configures IPV6 and also point to us complete AT commands list and their response which has support in SLM.

Thanks & regards,

Hi Praveen.

Yes, it supports IPV6. The AT command which configures IPV6 is +CGDCONT.

The documentation states the following AT commands as supported:

• Generic proprietary AT commands

• BSD Socket proprietary AT commands

• TCP/UDP proxy proprietary AT commands (optional)

• ICMP proprietary AT commands

• GPS proprietary AT commands

• MQTT client proprietary AT commands

• FTP client proprietary AT commands

In addition to this, all nRF91 modem AT commands are also supported, which can be found here.

Best regards,

Marte

Thank you Marte Lokken for quick response.

I have another query on SLM

I recently has check out latest master branch and using SLM application on devkit nRF9160 board with external MCU

so enabled configuration in prj.config file as mentioned in 

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/serial_lte_modem/README.html

CONFIG_SLM_GPIO_WAKEUP=y
CONFIG_SLM_CONNECT_UART_2=y
CONFIG_UART_2_NRF_HW_ASYNC_TIMER=2
CONFIG_SLM_TCP_PROXY=y
CONFIG_SLM_UDP_PROXY=y

and UART pins & Baud rate

, 19200 Baud rate changed in overlay file.

nRF9160 DK board is not responding with the AT commands with above configuration.

After checking the SLM application,prj.config file and overlay file for one hour, found that if CONFIG_SLM_GPIO_WAKEUP=y is commented in prj.config file then nRF9160 DK board responding to AT command.

This is because when CONFIG_SLM_GPIO_WAKEUP is set, the nRF9160 is asleep and you have to wake it up from the external MCU. There is an example for the nRF52 here if you want to see how this can be done.

nrf_gpio_cfg_output(WAKEUP_GPIO_PIN);
nrf_gpio_pin_clear(WAKEUP_GPIO_PIN);

nrf_gpio_cfg_output is used to configure the pin as output, and nrf_gpio_pin_clear is used for clearing the pin.

Best regards,

Marte
