OTAA with ISP4520

[ericlangel]

Hello,

i have an ISP4520 Module and a Dragino LPS8 Gateway
APB is working
but with OTAA i cant join.
App Key and Device EUI are both MSB

here is my hwconfig:

 // Define the HW configuration between MCU and SX126x
  hwConfig.CHIP_TYPE = SX1261_CHIP;     // Example uses an eByte E22 module with an SX1262
  hwConfig.PIN_LORA_RESET = PIN_LORA_RESET; // LORA RESET
  hwConfig.PIN_LORA_NSS = PIN_LORA_NSS;   // LORA SPI CS
  hwConfig.PIN_LORA_SCLK = PIN_LORA_SCLK;   // LORA SPI CLK
  hwConfig.PIN_LORA_MISO = PIN_LORA_MISO;   // LORA SPI MISO
  hwConfig.PIN_LORA_DIO_1 = PIN_LORA_DIO_1; // LORA DIO_1
  hwConfig.PIN_LORA_BUSY = PIN_LORA_BUSY;   // LORA SPI BUSY
  hwConfig.PIN_LORA_MOSI = PIN_LORA_MOSI;   // LORA SPI MOSI
  hwConfig.RADIO_TXEN = RADIO_TXEN;     // LORA ANTENNA TX ENABLE
  hwConfig.RADIO_RXEN = RADIO_RXEN;     // LORA ANTENNA RX ENABLE
  hwConfig.USE_DIO2_ANT_SWITCH = true;    // Example uses an CircuitRocks Alora RFM1262 which uses DIO2 pins as antenna control
  hwConfig.USE_DIO3_TCXO = false;        // Example uses an CircuitRocks Alora RFM1262 which uses DIO3 to control oscillator voltage
  hwConfig.USE_DIO3_ANT_SWITCH = true;   // Only Insight ISP4520 module uses DIO3 as antenna control
  hwConfig.USE_RXEN_ANT_PWR = false;

are there any known issues with ISP4520?

If you can connect with ABP, then your connection is correct.
My guess is

• is the device set to OTAA mode?
• is the device registered as OTAA device in your LoRaWan server?
• did you make sure that the DevEUI, AppEUI and AppKey of the device are the same used in your LoRaWAN server when you registered the device there?

is the device set to OTAA mode?

yes
err_code = lmh_init(&lora_callbacks, lora_param_init, true, CLASS_A, LORAMAC_REGION_EU868);

is the device registered as OTAA device in your LoRaWan server?

yes, we have a lot (more than 1000) of LoRaWan devices with ABP and OTAA. Its our first device with ISP4520 and your Lib

did you make sure that the DevEUI, AppEUI and AppKey of the device are the same used in your LoRaWAN server when you
registered the device there?

i got the DevEUI and AppKey from our Server
i have no AppEUI. On a Nrf52840 with RFM95 with a different Library i didnt needed it.

[ericlangel]

any idea?

[beegee-tokyo]

Is the device registered as OTAA device in your LoRaWAN server?

[ericlangel]

yes.

We also tried a working DevEUI and AppKey of a different device which was working before.
With this 2nd key i also tried all 4 combinations of LSB/MSB

Which LoRaWAN Mac Version are you using?
We are using Version 1.0.1

[beegee-tokyo]

I don't know.
I am using this library every day with nRF52840 devices without problems.
I do not have anymore ISP4520 modules to test

[fabltd]

Did you fix this.

It seems that the Lib has stopped connecting.

[beegee-tokyo]

Try an older version.
It works fine here in my everyday projects with nRF52840, ESP32 and RP2040 MCU's.
I can't test nRF52832, I don't have anymore boards with it.
