Frequently asked questions

The module communicates with the host MCU over a UART interface, configured at 9600bps baud rate, 8-bit data, no parity bit, 1 stop bit, and no flow control.

To switch ON, assert POW_EN high after the 5V supply has settled, then wait for 5ms before sending AT commands. To switch OFF, pull POW_EN low and wait at least 10ms before attempting to power ON again.

Firmware can be updated by either pulling pin 16 (STATUS) low at startup to enter XMODEM mode via UART at 115200bps, or by entering the AT$FW=1 command while the Sigfox AT command interface is running, which then puts the module into XMODEM mode for updating.

For RCZ2, the recommended settings are AT$IF=902200000 for transmission frequency and AT$400=1,0,0,1 for Sigfox configuration words. Ensure the RCZ region is set by AT$RCZ then execute AT$O=1,X.

The Uplynx-M-RCZ24 module has a typical maximum output power of 22dBm.
