LENA-R8001-00C - u-blox

LENA-R8001-00C Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the LENA-R8001-00C module?
  The recommended power-on sequence is to first apply the power supply voltage (VCC) and then the backup battery voltage (VBACKUP). This ensures that the module's internal voltage regulators are properly initialized.
• How do I configure the module's UART interface?
  The UART interface can be configured using the module's AT commands. The default baud rate is 115200, but it can be changed using the AT+IPR command. Additionally, the UART interface can be configured for flow control and other parameters using the AT+IFC command.
• What is the maximum current consumption of the LENA-R8001-00C module?
  The maximum current consumption of the module is approximately 450 mA during GPS acquisition and 250 mA during continuous tracking. However, the actual current consumption may vary depending on the operating conditions and the number of satellites in view.
• How do I implement antenna detection and switching on the LENA-R8001-00C module?
  The module has a built-in antenna detection feature that can be enabled using the AT+ANTDET command. The module can automatically switch between the internal and external antennas based on the antenna detection signal. The antenna detection signal can be connected to the ANT_DET pin on the module.
• What is the accuracy of the LENA-R8001-00C module's GPS receiver?
  The module's GPS receiver has a typical accuracy of 2.5 meters CEP (Circular Error Probable) and 5 meters SEP (Spherical Error Probable) under open-sky conditions. However, the actual accuracy may vary depending on the satellite geometry, signal strength, and environmental conditions.
