Looking for nRF9160 SLM hex file and source code

[sravan.rikka]

1. Planning to use nrF9160 SLM into our product, looking for SLM hex file but didn't get it online. Can you please share the nRF9160 SLM hex file or provide the link where can we get it.

2. I have tried to compile the serial lte modem sample code located at "\nrf\applications\serial_lte_modem" but the hex file is didn't generated. Am I missing anything?

Hi Sravan,

1. Planning to use nrF9160 SLM into our product, looking for SLM hex file but didn't get it online. Can you please share the nRF9160 SLM hex file or provide the link where can we get it.

Here are two ways to program nRF9160 DK with a prebuilt .hex:

Program using Cellular Monitor

1. Open the app Cellular Monitor from nRF Connect for Desktop.
2. Select your device to the upper left.
3. Scroll down to the white Program device button under Advanced options.
4. Then select Serial LTE Modem and program the device, with or without the corresponding modem firwmare.

Quick Start

1. Open Quick Start, found in nRF Connect for Desktop.
2. Follow or skip steps until you are asked to select application
3. Choose AT Commands to get Serial LTE Modem.

2. I have tried to compile the serial lte modem sample code located at "\nrf\applications\serial_lte_modem" but the hex file is didn't generated. Am I missing anything?

The build folder in your project folder should contain the .hex files. The file merged.hex contains the built applilcation including bootloader.

Exercise 2 in the nRF Connect SDK Fundamentals course at DevAcademy takes you through the steps to build and flash a sample.

Hi Team,

I have looked at the terminal output in visual studio and it shows the FATAL error. What am I missing anything?

I am able to build 'blinky' sample code successfully but getting FATAL error when I have build the 'serial_lte_modem' sample code. Can you please guide me to build successfully.

Hello,

Did you find anything wrong in  the build log? Can you please respond.

Have you selected nrf9160_nrf9160_ns your builld target? Or are you building for a custom board?

This looks like where the build starts to fail:

C:/Sravan/Programs/GIT_Repository/CL5G/CL_R200/zephyr/include/zephyr/toolchain/gcc.h:81:36: error: static assertion failed: "Wake up pin not configured"
81 | #define BUILD_ASSERT(EXPR, MSG...) _Static_assert(EXPR, "" MSG)

Yes, I am using nRF9160dk_nRF9160_ns while build target. What is your suggestion to resolve this.

Please see the configuration options for serial_lte_modem. What happens if you set CONFIG_SLM_POWER_PIN before you build? Possibly like this: CONFIG_SLM_POWER_PIN=P0.30.

As an alternative, could you try downloading and building using nRF Connect SDK v2.6.0 and see if you have any more luck?

[sravan.rikka]

I have tried this CONFIG_SLM_POWER_PIN=P0.30. and got one additional error as below. Mt work is getting delayed, please do needful asap to resolve this issue.

Which nRF Connect SDK are you using?

Could you try to download a fresh copy of the relevant nRF Connect SDK version using Toolchain Manager and see if that helps.
