SM301PU1

Wireless Technology to Control and Monitor Anything from Anywhere™ SYNAPSE SM301 RF Engine Synapse’s SM301 RF Engines® are long-range, reliable, surface mount 868 MHz transmitter receiver modules. These small, low-powered modules can have a range of up to 1 mile and power consumption as low as 2µA. The SM301 RF Engines come pre-loaded with the Synapse SNAP® mesh network operating system and provide interoperability with all other SNAP RF Engines. SM301PC1 has chip antenna and SM301PU1 has U.FL antenna connector.

ERRATA Notice of potential SM301 radio problem with SNAP 2.4.20 and earlier If you turn the radio off and then back on using the rx() function in your scripts, then after invoking rx(True) your radio will experience poor performance caused by improper antenna control signals. How to correct radio problem: After invoking a rx(True) in your script, add the following two "radio pokes" to restore proper operation: pokeRadio(0x000c, 0x12) # GPIO_1 CONFIGURATION REG - set to TX pokeRadio(0x000d, 0x15) # GPIO_2 CONFIGURATION REG - set to RX © 2011 Synapse Wireless® All rights reserved.
