lom204

I ported the LoRaMac-node to the LOM204 (WISOL STM32L071+SX1276)

But i have a big question, TXD and RXD uses PA2 and PA3, if you look the board-config.h

#define UART_TX                                     PA_2
#define UART_RX                                     PA_3

i changed to PA_2 to PA_9, compiles, burn, but nothing echos on PA_9 pin of LOM204.

Something else that i have to modify ?

Thanks!

Have a look to see if your new board uses Uart1 or Uart2. There could be a mismatch.

On keil c i use UART1 and UART5 and works fine
On arduino c i use too UART1 and UART5 and works nice too

In the loramac-node code if you will have to ensure the uart port has been set. You may have to change it to uart1 or uart5.

LoRaMac-node/src/boards/B-L072Z-LRWAN1/board.c

Lines 127 to 128 in edff6ce

	UartInit( &Uart2, UART_2, UART_TX, UART_RX );
	UartConfig( &Uart2, RX_TX, 921600, UART_8_BIT, UART_1_STOP_BIT, NO_PARITY, NO_FLOW_CTRL );

Do you mean change UART_2 to UART_5 and UART_TX to PA_9 and UART_RX to PA_10 ?

btw

You may have to change UART_2 to UART_1. UART_5 is not defined(it can be defined by you as necessary) and since you have UART_1 accessible, you might as well use it.

Looking at your blog, it looks like the code is from a long ago release of the LoRaMAC node code, and so I would recommend moving to using the latest code on this repo.
