SetTx Illegal Status Arduino Uno
Hi, I am trying to implement your code on this module which has sx1262 chip. When I upload the code, I'm getting the following error. Can you please help.

SX126x_SPI_SELECT=5
SX126x_RESET=6
SX126x_BUSY=7

SetTx Illegal Status
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.
Hello! I am getting the same error... Can you share your solution?? Even after enabling LDO mode following is the message displayed:
begin debugPrint=0 SX126x_SPI_SELECT=5 SX126x_RESET=6 SX126x_BUSY=7 SX126x_TXEN=-1 SX126x_RXEN=-1 Reset syncWord=0x1424 SX126x installed tcxoVoltage=0.00 useRegulatorLDO=1 SetTx Illegal Status
If this change doesn't work, I don't know how to solve it.
/*
int16_t ret = lora.begin(RF_FREQUENCY, //frequency in Hz
TX_OUTPUT_POWER); //tx power in dBm
*/
int16_t ret = lora.begin(RF_FREQUENCY, //frequency in Hz
TX_OUTPUT_POWER, //tx power in dBm
3.3, //use TCXO
true); //use TCXO
If this change does not resolve the issue, you may need to configure these appropriately.
SX126x_TXEN=-1 SX126x_RXEN=-1
It still gives following error:
begin debugPrint=0 SX126x_SPI_SELECT=5 SX126x_RESET=6 SX126x_BUSY=7 SX126x_TXEN=-1 SX126x_RXEN=-1 Reset syncWord=0x1424 SX126x installed tcxoVoltage=3.30 useRegulatorLDO=1 SPI Transaction error:10 SPI Transaction error:10 SetRx Illegal Status
Btw I have not connected any of the TXEN or RXEN pin of LoRa. The DIO pins are also disconnected.

DIO4 is transmit enable pin.
Still not working... I instead used the RadioLib library which is working fine...
