As a point of comparison, using the nrf9151-DK
it works - at the same exact location
@rabarar can you email me your IMEI. A picture of the setup would be helpful as well.
@rabarar also could be the antenna rather than the board. Do you have any other active U.FL antennas you can try?
Can you also make sure that if you search your /gps/build/
directory that CONFIG_MODEM_ANTENNA_AT_COEX0
exists in your .config
file? The .config
file is a compilation of all your kconfig values.
I assume you didn’t hook up anything else to that port at any time?
I replaced your antenna with a known working one and see that I can get a fix - the antenna that you shipped was defective…

@jaredwolff as a suggestion it might be better to just ship a case with U.FL-SMA female connectors. I drilled a hole in your case, threw one on and used that with a better antenna … I’ll send you a pic if you’re curious to see it!
rabarar I replaced your antenna with a known working one and see that I can get a fix - the antenna that you shipped was defective…
Ok. I’ll get a return label and replacement to you ASAP. Same address as your order OK?
jaredwolff no rush, same address works fine
