SetTx Illegal Status Arduino Uno

[johnpiker]

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.

begin
debugPrint=0
SX126x_SPI_SELECT=5
SX126x_RESET=6
SX126x_BUSY=7
SX126x_TXEN=-1
SX126x_RXEN=-1
Reset
syncWord=0x1424

tcxoVoltage=0.00
useRegulatorLDO=0
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:

SX126x_RESET=6
SX126x_BUSY=7
SX126x_TXEN=-1
SX126x_RXEN=-1

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:

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

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...
