In the case of UHF RFID handheld readers and tags, I get error messages while writing to the tags. How can I get a return signal strength indicator value?
To answer your question, I reached out to Sanjiv Due, the president and CEO of RFID4U, a leading training and system integration company. Here is Sanjiv’s response to your question: “It depends on the reader’s software development kit. Some reader manufacturers choose to expose the return signal strength indicator (RSSI) as a return parameter, and others do not. For example, when executing a write command with the Zebra RFD8500 SDK, as part of the return response, there is an object called tagData which contains something called m_PeakRSSI, which can be used to obtain the RSSI. Other readers do not have this.” I hope that answers your question.
