EC200UCNAA firmware

I need the Firmware for EC200UCNAA-N05-SGNSA.
Here is my current firmware(QuecPython):
EC200UCNAAR02A02M08_OCPU_PY
The current firmware doesn’t enable internal GNSS. I thought it should be a firmware problem as the SGNSA partition of the part number suggest it should have internal GNSS and the QuecPython version already have supported internal GNSS.

import quecgnss
import utime

“”"
Currently only EC200UCNAA EC200UCNLA/EC200UEUAA models support this feature
“”"
def main():
ret = quecgnss.init()
if ret == 0:
print(‘GNSS init ok.’)
else:
print(‘GNSS init failed.’)
return -1

ret = quecgnss.gnssEnable(0)
print("gnssEnable(0)",ret)

ret = quecgnss.gnssEnable(1)
print("gnssEnable(1)",ret)

for i in range(3):
    ret = quecgnss.get_state()
    print("get_state():", ret)
    while ret != 2:
        utime.sleep_ms(1500)
        ret = quecgnss.get_state()
        print("get_state():", ret)
    data = quecgnss.read(4096)
    print(data[1].decode())
    utime.sleep_ms(2000)

# ret = quecgnss.gnssEnable(1)
# print("gnssEnable(1)", ret)
ret = quecgnss.gnssEnable(0)
print("gnssEnable(0)",ret)

if name == ‘main’:
main()

It can be tested

Refer to the above code

OK, I’ve checked it with the other parts I have and it is fine. It seems that there’s a problem with the first one, which results in disabling the internal GNSS module. Do you have the original firmware for EC200UCNAA-N05-SGNSA?
