Option with SX1262/1268

LoRa modules with SX1262/1268 have several options.

Using TCXO(Temperature-Compensated Crystal Oscillator)
SX1262/1268 can use the TCXO.
If the TCXO is used, the XTB pin is not connected.
However, the 6th pin (DIO3) of the SX1262/1268 can be used to power the TCXO.
Explanation for TXCO and antenna control is here.
Ra-01S / Ra-01SH does not use TCXO.
Power supply modes
SX1262/1268 has two power supply modes.
One is that only LDO used in all modes.
Another is that DC_DC+LDO used for STBY_XOSC,FS, RX and TX modes.
Explanation for LDO and DCDC selection is here.
Ra-01S / Ra-01SH use only LDO in all modes.
RF-Switching
In general, use DIO2 to switch the RF-Switch.
However, some tranceiver use an external gpio to switch the RF-Switch.
Ra-01S / Ra-01SH use the SC70-6 integrated load switch to switch between RFO and RFI.
Ra-01S / Ra-01SH use DIO2 to control this.
DIO2 = 1, CTRL = 0, RFC for SC70-6 goes to RF1 --> Switch to Tx Mode.
DIO2 = 0, CTRL = 1, RFC for SC70-6 gose to RF2 --> Switch to Rx Mode.

You need to look at the schematic to set these options properly, but it's very esoteric.
The default settings for this library are for Ra-01S / Ra-01SH.
When using other than Ra-01S / Ra-01SH, you need to set them appropriately.

Surbhidk commented 1 year ago

yeah.. got it . now its working for me Changes i have done :- Kconfig.projbuild:

config USE_TCXO
    bool "Enable TCXO"
    default false
    help
        Enable TCXO.

LoRaInit();
//int ret = LoRaBegin(915000000, 22, 0.0, false);
int8_t txPowerInDbm = 22;
float tcxoVoltage = 0.0; // don't use TCXO
bool useRegulatorLDO = false; // use only LDO in all modes

if CONFIG_USE_TCXO // Use external tcxo at 3.3v alimentation.

tcxoVoltage = 3.3; // use TCXO
useRegulatorLDO = true; // use TCXO

endif

//LoRaDebugPrint(true);
int ret = LoRaBegin(frequencyInHz, txPowerInDbm, tcxoVoltage, useRegulatorLDO);
ESP_LOGI(TAG, "LoRaBegin=%d", ret);

Now, I have one more question: How do I create a mesh connection in this?

nopnop2002 commented 1 year ago

Unfortunately this library does not support meshes.

Your PR is welcome.

Surbhidk commented 1 year ago

In lora chip SX1276 , it can receive multiple device data. Is there any changes to make for SX1262 library for SX1276 is https://github.com/nopnop2002/esp-idf-sx127x

My logs for SX1272 : I (209458) task_tx: 11 byte packet sent... Sent data=456!! 20910 Received Data :123!! 21322 Received Data :894 7768 I (211518) task_tx: 11 byte packet sent...

Could you please check the Lora receive function of both lora chip and inform me about the respective changes?

nopnop2002 commented 1 year ago

I don't quite understand your problem.

Surbhidk commented 1 year ago

I am using two LoRa chips, SX1276 and SX1262. In the SX1276 code, it can receive data from two devices simultaneously, as shown in the above logs. However, when I try the same with the SX1262, it only receives data from one device at a time.

nopnop2002 commented 1 year ago

I will investigate.

Surbhidk commented 1 year ago

Hello , Do you how to convert rssi to distance . Any formula?

nopnop2002 commented 1 year ago

@Surbhidk

rssi has nothing to do with distance.

RSSI changes depending on antenna performance, etc.

Surbhidk commented 1 year ago

Then how to calculate distance between two lora device ? Can we do that ?

nopnop2002 commented 1 year ago

We can't.

ABHITHLALC commented 8 months ago

@nopnop2002 I'm facing the same issue trying to use this code with my SX1262 LoRa module, the Waveshare Core SX1262-868, and an ESP32 using the ESP-IDF framework. Can I use this library for my module? If yes, how can I adapt it? What should be the pin configuration? Any help would be greatly appreciated.

nopnop2002 commented 8 months ago

Can I use this library for my module?

I don't have Waveshare Core SX1262-868. I'm not sure if this repository will work properly.

What should be the pin configuration?

Another is that DC_DC+LDO used for STBY_XOSC,FS, RX and TX modes.
Explanation for LDO and DCDC selection is here.
Ra-01S / Ra-01SH use only LDO in all modes.
RF-Switching
In general, use DIO2 to switch the RF-Switch.

ABHITHLALC commented 8 months ago

Is this intended for point-to-point LoRa communication or communication between LoRa nodes and gateways? or both?

nopnop2002 commented 8 months ago

Both.

ABHITHLALC commented 8 months ago

Thank you for the clarification. Do you know what modifications needed to use this library for communicating the device to the gateway?

nopnop2002 commented 8 months ago

These act as gateways.

ABHITHLALC commented 8 months ago

I apologize for any confusion. I was wondering if this is intended for the connection of LoRa devices to a LoRaWAN network server through LoRa gateway . Your clarification would be greatly appreciated. Thank you

nopnop2002 commented 8 months ago

This repository does not support LoRaWAN.

ABHITHLALC commented 8 months ago

Thank you for your response. 😊

i stumbled across same problem and idk why but by setting
lora.DebugPrint(true); my errors were resolved and one more thing to mention use voltage level shifter (it might be a issue too)
