Hello LF'ers, My newly arrived Ublox 8 and breakout board has landed and I have had a very quick play with it and the Ublox UCentre software. I have set Time0 to give say a 1 mHz output in UBX / CFG
Hi Chris, LF 1 mHz? Maybe 1 MHz: TP frequency must be in the range 0.25 Hz..10 MHz. In TP5 settings, toggle frequency and duty cycle flags then set 1000000 Hz and 50% d.c. in the f. locked fields. Pr
Hello Riccardo, Thanks, a typo on my phone, I am always doing it, sorry, I was setting 1 MHz (mega) :) I'll try again but that sounds like I was doing it correctly. Where should the probe ground be t
Chris, See https://www.u-blox.com/sites/default/files/NEO-LEA-M8T-FW3_DataSheet_%28UBX-15025193%29.pdf and connect your probe (of the scope) directly to the pins. Am 04.01.2019 18:45, schrieb Chris W
Ok, Chris, it's correct to connect the ground probe as near as possible to the module's GND. Please, could you post some pics of your NEO's breakout board? 73 de Riccardo IW4DXW Il giorno Ven 4 Gen 2
Hello Riccardo, Thanks to you and Stefan for the replies. I saw a silly error where I had "Other setting in GNSS Time Locked Mode" ticked but the default 1Hz set in that menu. I can now order frequen
Hi Chris, Well, only the NEO-M8T version has the TP2 functionality (readly available by default settings). -pin 3 (TIMEPULSE) of the Ublox module is often connected to a SMD green LED (in series with
Hello Riccardo, There's definitely continuity from both output pins of the Ublox to the break out board pads, and it is a -T model. I have tried probing on the TP2 pin itself on the Ublox though with
Chris, Did you already contact the distributor? You know, Paul mentioned he has been in contact with him, so it seems to be possible to report about this problem and ask for advice directly. 73, Stef
Hello DK7FC, I'll try a refresh to the default, if nothing I will indeed get in touch with them, cheers Stefan. -- Best regards, Chris mailto:[email protected]
Hello LF'ers NOW FIXED!! :) It appears some come with a solder jumper on the back of the GPS board. Alexander got in touch from CSG Shop and said to remove the jumper solder blob. I did and it now wo
Hi Chris, I'm glad you fix it, thank you for the info. I'm curious, Chris: what the blob was shorting? If you're planning on using 2nd timepulse, remember to decouple TP2/SAFEBOOT pin with an adequat
Hello Riccardo, Thanks, a good point I will be sure to bear in mind! I have further info so will copy paste what i posted to the "Time Nuts" forum in case it helps anyone else. ~~~~~~~~~~~~~~~~~~~~~~
