Janos, thanks for your quick answer.
The sensor board MTS420 use the UART1 of mica bus, therefore it isn't possible to switch to UART0 of mica bus. At tinyOS 1.x it works with UART1 well. I'm not sure what you mean with "USART1 is used by the radio (in SPI mode)" I thought the communication between atm1281 and rf230 happen about SPI-bus. Use the IRIS mote the USART1 interface for SPI? I ask because the atm1281 have a seperate SPI port, therefore I thought it should exist any restrictions for using UART1 and SPI from the hardware layer. Exists any possibility in tinyos 2.x to use SerialActiveMessage (UART0), USART1 (raw data) and SPI for radio together? Or, where can I find more information about communication by UART1 in SPI mode?
