The iccid() function only works after an attach command is attempted. Since we use the ICCID to determine the correct APN to use in the attach command, we have to do a dummy attach call, read the iccid, detach, and then correctly attach with the computed apn. Hope this helps others until this issue is resolved.

Below is the revised code that now works.

from network import LTE
lte = LTE()
lte.reset()
lte.init()
sleep_ms(1500)
iccid = lte.iccid()    # does not work
lte.attach(apn='unknown')    # attempt attach so iccid() will work
sleep_ms(1500)
iccid = lte.iccid()    # iccid() now works
lte.detach(reset=False)
# compute apn from iccid
lte.attach(apn=computed_apn)    # attach  with correct apn

Where can I get the GPy-1.20.0.rc9.tar.gz file? The file is not found on the downloads web page Downloads GPy.

We have done extensive testing of our product with this version and have shipped production units. Now we have purchased new GPy's and when I try to use the Firmware Update Tool version 1.15.2.b1 with development releases checked, the 1.20.0.rc9 option is not available.

Any help would be appreciated. We will update and test our program to work with newer releases later, but for now we need to use the well tested version. I know it was a beta version, but for our purposes it worked well. The production version at the time had issues which the beta version solved.

Found the answer to my question. If I select the stable version in the Firmware Upgrade Tool and then select the Type/Version to development, I get the option to select 1.20.0.rc9.
