Facing Error: RA01S: SPI Transaction error:10 #2

Open testqaibs opened 2 years ago

testqaibs commented 2 years ago

I am using tried using ESP32-WROOM-32D and ESP32-C3-13 devices with LoRa1262 chipset. I am facing RA01S: SPI Transaction error:10. Please let me know if I am missing anything.

Following logs printed on COM port:

If you enable this, you will get more information.

I (3425) RA01S: syncWord=0x1424

SyncWord is the correct value.

The wiring seems to be correct.

The wire cable may be too long.

Thanks for the quick reply. I have enabled LoRaDebugPrint, now I am getting following logs:

I (315) main: Frequency is 433MHz

The frequency is different between RA-01S and RS-01SH.

This is my log

Perhaps your wire cable is too long

Thanks for giving your logs for comparison and timely replies. I am using LoRAa1262F30-915 chipset i.e from G-NiceRF. Hope this chipset is also supported with this code.

SX1262 has 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](https://github.com/beegee-tokyo/SX126x-Arduino).
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](https://github.com/beegee-tokyo/SX126x-Arduino).
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 to RF1 Tx Mode.
DIO2 = 0, CTRL = 1, RFC to R21 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.

I am using LoRAa1262F30-915 chipset

Is the schematic published?

I want to see the schematic inside the LoRa1262F30 Without seeing this, the following cannot be judged.

This is Ra-01S internal schematic.

If you look at this, you can see the following.

Ra-01S / Ra-01SH does not use TCXO. Ra-01S / Ra-01SH use only LDO in all modes. 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.

nopnop2002 commented 2 years ago

I saw Product Spec.

If tcxoVoltage is set to a value other than 0, TCXO will be used, but I don't know what value is appropriate. The Product Spec does not mention this.

If useRegulatorLDO is set to true, DC_DC+LDO used for STBY_XOSC,FS, RX and TX modes. The Product Spec does not mention this.

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

mx-cyber commented 2 years ago

Do you have a solution to this problem？

nopnop2002 commented 2 years ago

No.

I don't know the proper value for tcxoVoltage.

If you know the appropriate value of tcxoVoltage of your Lora module, it will work.

    float tcxoVoltage = ???; // use TCXO
    bool useRegulatorLDO = true; // use TCXO
    int ret = LoRaBegin(frequencyInHz, txPowerInDbm, tcxoVoltage, useRegulatorLDO);

OK, thank you very much for your reply
