Abstract

The invention discloses a board-level radio frequency performance testing method of a BLE device. The method enables a system host computer to control a BLE test frame and a BLE device to be tested through an HCI interface; enter the BLE device to be tested into a DTM mode; and then target the BLE device The transmission power is measured at the low, medium and high frequency points to obtain the corresponding transmission power, and judge whether the transmission power of the BLE device to be tested meets the standard; also judge whether the received bit error rate of the BLE device to be tested meets the standard; the test The data is stored in the database. The invention can automatically test the RF performance of the BLE device according to the radio frequency test items specified in the Bluetooth protocol standard V4.2, better evaluate the performance of the radio frequency transceiver of the BLE device, and save relevant test data.

Description

technical field [0001] The invention belongs to the technical field of testing radio frequency equipment, and particularly relates to a method for testing board-level radio frequency performance of BLE equipment. Background technique [0002] With the development of the Internet of Things, low-power BLE, as a short-range wireless communication solution, has received more and more attention from the market. The use of low-power BLE in new market segments of wireless accessories or wireless products, including personal health and wellness devices, advertising, indoor positioning, and proximity tags, is a booming trend. [0003] Since low-power BLE technology is a wireless technology, there are problems such as long test time and inconvenience in its production test process. Especially for the evaluation of the radio frequency performance of the chip, it is necessary to use an expensive and complex wireless communication tester for testing, and the test cost is high and the ti...
