Quectel L76GAB issue with SPI protocol

IoT Modules GNSS Module

Hi, i am using Quectel L76GAB communication by SPI, and requesting NMEA data every 5 seconds.
When the SPI reads a size higher than 8K, the unique way to get valid data again is resetting module.
Any idea about how to get module working properly after buffer is full?

Thanks.

Hi PabloHR
If the read data exceeds the buffer size, there are two ways to restore the module to normal.

  1. Reset the module, power off or control the reset pin.
  2. Read all the data in the buffer, and then send any data or command to wake up the module.
