RE: Using Nrf52832 board with a RS485 to UART TTL converter without the DE/RE pins

Hi Edvin,

I have solved the problem the with the converter, but I still have an issue with initialization of the sample code. I keep getting

*** Booting nRF Connect SDK d96769faceca ***
[00:00:00.270,385] <err> modbus_serial: Failed to configure UART
[00:00:00.270,385] <err> modbus: Failed to init MODBUS over serial line
[00:00:00.270,416] <err> mbc_sample: Modbus RTU client initialization failed

I have also described the problem in another Thread. If you have any solution for it, that would be a great help.

Regard

Cipher

Hello,

Sorry for the late reply, but I wanted to see if anyone in the community chipped in first (as the ticket will have less visibility once answered). Hopefully, if someone knows about this device, they may still reach out.

If you have any concrete questions, I may be able to help. But I have no previous experience with this device.

BR,

Edvin
