I really appreciate your attention, thank you. So, from the problem I got, is there a solution or configuration that I missed so that the nodes can send data with OTAA to the server / gateway with dual core or single core. I am reading and testing the code with the self-test ( and the code did not work. On this board, I'm not using TCXO and DCDC. Currently, I am working with the sensor BME 688 with the board Nucleo-WL55JC1. But there is no response / action from the node sending data to the server / gateway with OTAA. Meanwhile, for the single core STM32WLE5CBU6 MCU end node, the program was successfully uploaded with the Lora protocol configured. ![]() I have followed the solution steps given from this topic: On the external terminal via serial usb and couldn't send data to the server / gateway with OTAA. NUCLEO-WL55JC1 Databrief (PDF) NUCLEO-WL55JC1 Active STM32 Nucleo-64 development board with STM32WL55JCI MCU, SMPS, supports Arduino and morpho connectiv. On creation, make sure LoRaWAN version is 1.0. Please check the CM4\MbMux\mbmuxif_sys.c or update the scatter file" Choose STMicroelectronics -> Nucleo-WL55JC1->1.0 -> v1.0.0 ->EU868870 Choose Frequency Plan Europe 863-870 MHz (SF9 for RX2) Generate a JoinEUI with and click Generate on remaining keys. A dual-power output and a wide linear frequency range ensure worldwide compatibility. "WARNING: There is a difference between the MAPPING_TABLE placement in memory: 0x20008000Īnd the address calculated according to the IPCCDBA option byte: 0x2003FFF0 The STM32WL55 line includes a wide variety of communication features including up to 43 GPIOs, an integrated SMPS for power consumption optimization, multiple low-power modes to maximize battery life. After I uploaded the LoRaWAN end node program to the STM32WL55JC1 (dual core) development board, it said The program from the example project has been uploaded successfully. I have configured LoRaWAN end node protocol parameters like this documentation ( ). I'm using Nucleo-WL55JC1 STM32WL development board for LoRaWAN end node dual core and i have a custom board with MCU STM32WLE5CBU6 for LoRaWAN end node single core.
