| 问题描述: Following the work order #LZV464009454770: I have two modules: EC200UCNAA and EC200UCNLA. I can confirm that the EC200UCNAA has internal GNSS enabled bec*se with the original firmware (which it doesn't have anymore) it sent the GNSS data through the serial port. I didn't check the EC200UCNLA for the internal GNSS with original firmware and it doesn't have the firmware anymore too. Although you said not to program QuecPython firmware between variants, as I don't have EC200UCNLB or EC200UEUAB, I risked and programmed both firmware(CNLB and EUAB) on both modules, and both more or less are working. The only downside is the connection to the cellular network in EC200UCNAA which becomes problematic and makes it either not to register to the network or register in 2G mode with very low signal reception. I programmed both firmwares(EC200UCNLBR01A02M08_PY and EC200UEUABR01A02M08_PY) on both devices I have (CNAA and CNLA) and checked yo* instruction. init() ret*n 0. read(2048) ret*ns (0, ''). gnssEnable(0) or gnssEnable(1) ret*ns -1. get_state() also ret*ns 0. |

According to what I said before, only EC200UCNLB and EC200UEUAB currently support QuecPython development. It is recommended to use the corresponding module development. And for EC200UCNLB and EC200UEUAB，the built-in GNSS function is not supported, You can read external GNSS data through GNSS API library(https://python.quectel.com/wiki/#/en-us/api/QuecPythonClasslib?id=gnss-navigation-positioning-and-timing) |
