Are you talking about here, with two devices, one set to APP_MODE_RX and the
other set to APP_MODE_TX?

Well, I tested the receive with other module transmitting lora, but not running

Hi all, I am happy to announce that the licenses are migrated to Apache and the remaining ones are documented in the LICENSE file It would be good If someone can run a FOSSID scan to double check the licenses (in case I missed something) then I think that we can remove the DISCLAIMER-WIP from NuttX and start the NuttX 10.3 release process Best regards Alin -Original Message- From: Nathan Hartman Sent: den 9 februari 2022 19:14 To: dev@nuttx.apache.org Subject: Re: Graduation?

Re: nuttx lora sx127x device use for help
You just need two devices a tx and a rx. Look the sx127x demo app source code, you need to run the other as tx.

NuttX and C++ libraries: boost / ASIO / std::chrono
Hello team, I would like to ask who has used C++ libraries with NuttX. For example if I have a C++ application that is based on boost and std::chrono then what should be a good way of starting it with NuttX? Best regards, Petro
Re: NuttX and C++ libraries: boost / ASIO / std::chrono
We use both uClibc++ and libc++, both work fine. But never try the boost library.

Re: nuttx lora sx127x device use for help
If you configure created the initialization file, like: boards/arm/stm32/stm32f4discovery/src/stm32_sx127x.c And added the SPI chip to control your device, see CONFIG_LPWAN_SX127X at: see boards/arm/stm32/stm32f4discovery/src/stm32_spi.c Then the communication should work. Do you have a logic analyzer to see if there is communication over SPI line?

Error when building custom board
Hi guys, I am having problems building custom boards outside of the Nuttx folder tree. Usually I use the following folder structure. |-> apps |-> my-folder |-> my-apps |-> custom-app |-> my-boards |-> custom-board |-> nuttx To build my apps I just need to create a symbolic link called external inside apps folder. To create a new custom board I start copying a similar board (e.g nucleo-g431kb) to my-boards folder and make the following changes *remove from defconfig:* CONFIG_ARCH_BOARD="nucleo-g431kb" CONFIG_ARCH_BOARD_NUCLEO_G431KB=y *add on defconfig:* CONFIG_ARCH_BOARD_CUSTOM=y CONFIG_ARCH_BOARD_CUSTOM_DIR="../my-folder/my-boards/custom-board" CONFIG_ARCH_BOARD_CUSTOM_DIR_RELPATH=y CONFIG_ARCH_BOARD_CUSTOM_NAME="custom-board" *Rename src/Make.defs to src/Makefile and append the line * include $(TOPDIR)/boards/Board.mk at the end of file. This works well for me up to Nuttx version 10.2.0 but now when I try to make I got the errors make[1]: Entering directory '/home/daniel/nuttx-workspace/nuttx/tools' make[1]: Leaving directory '/home/daniel/nuttx-workspace/nuttx/tools' make[1]: Entering directory '/home/daniel/nuttx-workspace/nuttx/tools' make[1]: Leaving directory '/home/daniel/nuttx-workspace/nuttx/tools' Create version.h make[1]: Entering directory '/home/daniel/nuttx-workspace/nuttx/boards' make[2]: Entering directory '/home/daniel/nuttx-workspace/nuttx/boards/arm/stm32/common' Makefile:23: board/Make.defs: No such file or directory make[2]: *** No rule to make target 'board/Make.defs'.

Re: nuttx lora sx127x device use for help
That's what it used to be, but I used two boards to execute sx127x -r on one of the boards and sx127x -t on the other, expecting communication between the two boards, but it didn't work as expected . Do you need any other configuration? the first board: nsh> sx127x -t Start sx127x_demo LORA modulation Set frequency to 93000 Set power to 14 Send 5 bytes the sencond boad: nsh> sx127x -r Start sx127x_demo LORA modulation Set frequency to 93000 Set power to 14 Waiting for data It looks like it's stuck, and the message sent is not received. Is there something wrong with my configuration? Can you help me have a look? I've been doing it for a long time and haven't done it yet.
Re: nuttx lora sx127x device use for help
I tested the two devices with an oscilloscope and both have signals, but there is no communication between the two devices. One is always sending data, and the other is waiting to receive data. Does the communication between the two devices need to be networked first? That's what it used to be, but I used two boards to execute sx127x -r on one of the boards and sx127x -t on the other, expecting communication between the two boards, but it didn't work as expected . Do you need any other configuration? the first board: nsh> sx127x -t Start sx127x_demo LORA modulation Set frequency to 93000 Set power to 14 Send 5 bytes the sencond boad: nsh> sx127x -r Start sx127x_demo LORA modulation Set frequency to 93000 Set power to 14 Waiting for data
Re: Error when building custom board
Hi, Do you want to use board common code? There where some code tree restructurings to eliminate code duplication. There is an option to enable/disable common code in menu config. Please try to use it and feedback if it helps you.

Re: Error when building custom board
Please check the common/Make.defs file in-tree of the board you based your custom board on. There is a new variable introduced. (Sorry, writing from my phone. I'll try to send a direct link later.)

Re: Error when building custom board
Hello Jukka, So you experience the same problem as Daniel and reverting the commit helps? Before f77956a227f1db6ecb44eda3814e7b02aa2187a6 there was no way to reuse common code from "nuttx/board/...". I'm using a custom board based on SAME70 and after https://github.com/apache/incubator-nuttx/pull/4981 I found my code tree broken. Now the folder structure for "boards/arm/samv7" is the same as in "boards/arm/stm32". Here is what I did to get it back running: 1. Synced "custom-board/scripts/Make.defs" with "boards/arm/samv7/same70-xplained/scripts/Make.defs" 2. Renamed "custom-board/src/Makefile" to "custom-board/src/Make.defs" and synced with "boards/arm/samv7/same70-xplained/src/Make.defs" 3. Removed files in my code tree that have exactly the same implementation as files from "boards/arm/samv7/common" It seems like Daniel is hitting the same issue, so I expect that renaming Makefile to Make.defs plus setting "BOARD_STM32_COMMON=n" should fix the issue without any additional file clean-up. Please give me feedback if that helps.
