LoRa: Initial integration of LoRa Basics Modem for LoRa API & SX126x and SX127x #89241

JordanYates · 2025-04-29T08:26:42Z

This PR contains the initial integration of LoRa Basics Modem (Semtech's replacement for LoRaMAC-node) with Zephyr.

To limit the scope, only the LoRa API is considered, and only the standalone SX126x and SX127x chipsets are ported.
The new drivers use the same devicetree definitions as the current drivers, so the only change required to use the updated drivers is CONFIG_LORA_MODULE_BACKEND_LORA_BASICS_MODEM=y.

Once this PR is merged, we can start to look at:

Basic LoRaWAN support
Other LoRa transceivers (stm32wl)

PR has been tested with the lora send and receive samples between a semtech_sx1262mb2das and semtech_sx1272mb2das shield in both directions.
The SX1262 transmitter, SX1272 receiver setup currently receives packets with ~10dB lower RSSI than the reverse, which I will continue to look into.

Issue for the creation of the module: #89251.

I'm happy to give this a try with a non trivial application on the TTGO T-Beam board. Many thanks for doing the port to the new driver.

I can confirm that this properly works on this board (RX & TX). Had to switch the syncword in lbm_lora_config->params.sync_word though, but that is specific to my use-case (which BTW is already better than before where I needed to change this in the HAL).

Thanks for validating. I also have a use-case for changing the sync word, but I don't want to pile too many changes in this PR.
The only challenge will be how to add the functionality without breaking compatibility with the loramac-node backend, which will need to stick around for a while.

Sure, agree!

The only challenge will be how to add the functionality without breaking compatibility with the loramac-node backend, which will need to stick around for a while.

I would implement that using a new API function set_sync_word, which just returns a -ENOSUP if not implemented by a driver. But we probably better move that discussion to an issue.

Move the current implementation of the LoRa API using `loramac-node` to a dedicated folder in preparation for the LoRa basics modem implementation. Signed-off-by: Jordan Yates <jordan@embeint.com>

Import the lora-basics-modem module as an alternate backend for LoRa and LoRaWAN, since loramac-node has been deprecated. Support is currently limited and experimental. Signed-off-by: Jordan Yates <jordan@embeint.com>

As a first integration of the LoRa Basics Modem backend, implement the LoRa API for the standard SX126x/SX127x chips. Much of the logic from `lbm_common.c` is taken from the loramac-node `sx12xx_common` implementation, but it should now be agnostic for all LoRa RF transceivers.

Hi @JordanYates,

I'm testing this PR (#89241) on a custom board with an SX1262 for basic LoRa with the send and receive samples. I'm seeing a fatal exception and "LoRa send failed, -22" (EINVAL). This does not happen with loramac-node driver.

My Setup:

Board: ESP32S3 with SX1262.
LoRa Usage: LoRa Send/Receive samples.
Zephyr Version: 4.1.99

Relevant prj.conf:

CONFIG_LOG=y
CONFIG_LORA=y
CONFIG_PRINTK=y
CONFIG_LORA_LOG_LEVEL_DBG=y

Request:
My application code is the same as the samples with the addition of the return code when it failed. It would be helpful to me if you could enlighten or help me regarding this? Thanks for your work on this!

JordanYates · 2025-05-21T22:55:25Z

Thanks for taking the time to try it out @mirzasadiqassb.

Based on the provided logs, it looks like the TX done interrupt is not being seen by the micro. This is interesting since the logic works on my SX1262 shield. Can you run the test again with the LOG_DBG in sx126x_hal_write and sx126x_hal_read commented out so we don't drop the other messages, and also provide your version of the SX1262 devicetree node?

sophiekovalevsky · 2025-05-21T23:48:30Z

@JordanYates i will definitely give it a try on this but not during this week, for sure on next week.

Can you run the test again with the LOG_DBG in sx126x_hal_write and sx126x_hal_read commented out so we don't drop the other messages,

Here is the log when I commented out the LOG_DBG:

And here is my SX1262 devicetree node:

My best guess would be a problem related to the external TCXO configuration, which the MBed shield does not have. I should have access to hardware with an external TCXO in the next few weeks, so I can investigate further then.

Don't let that dissuade you from digging deeper if you want, I would appreciate any fixes :)

Running some initials tests is indicating that everything is so far so good.

Tests have been made on a custom board featuring sx1262.

	lora: lora@0 {
		compatible = "semtech,sx1262";
		reg = <0>;
		reset-gpios = <&gpio0 19 GPIO_ACTIVE_LOW>;
		busy-gpios = <&gpio0 20 GPIO_ACTIVE_HIGH>;
		dio1-gpios = <&gpio0 21 GPIO_ACTIVE_HIGH>;
		antenna-enable-gpios = <&gpio0 23 GPIO_ACTIVE_HIGH>;
		dio2-tx-enable;
		tcxo-power-startup-delay-ms = <5>;
		spi-max-frequency = <1000000>;
	};

I just forgot to bring another extra board to completely test the tx/rx modes.
