The Bluetooth Mate Gold & Silver are not longer aviable.
For this Tutorial i need an alternative GPS-RTK2 Hookup Guide - SparkFun Learn
Sparkfun tell me to use an ESP 32, and i dont know how?
What must i do to use it like the Bluetooth Mate Gold before?
Thank you very much for your Help!
If you just want to replace Sparkfun BR boards, you may just use an HC-05 BT module. You will have to configure it independently (for baud rate) before connecting it to the GPS-RTK2 board. Wiring is also not the same.
Hello Eric,
I found a Solution for me: Sparkfun WRL-23287 works exact like the Bluetooth Mate`s
Thank you for your Help, Michael
Thank you for pointing to that solution. I used Sparkfun BlueSMiRF board for my first rover but switched to HC-05 when BlueSMiRF have been retired. I didn’t noticed the new version released last year. Indeed, I have stability issues with the BT connection using the HC-05. Sometime, while driving (more in cities than in campaign), BT connection between rover and smartphone is lost. Usually, I switch the smartphone to airplane mode and back, and connection is back. It’s annoying. I may have a look at the BlueSMiRF v2 board.
BTW, did you noticed in the BlueSMiRF v2 presentation video that Nathan used it directly connected to the RTK board? (here)
Thank you for the Video.
You know Nathan, can you ask him to Update this Tutorial :
with the Information about the New BlueSMiRF V2 ,
the Alternative to expired Bluetooth Mate Gold/ Silver?
For all the “Newbies” (o;
Thank you very much.
With frendly Greetings, Michael

Thanks @Datatron and good point! I have updated the Hookup Guide with links to the BlueSMiRF v2.

BlueSMiRF v2 is sending and Receive the RTK Data, but there is NO RTK !!
Same System with Bluetooth Mate Gold works Perfect!
My OUT Ptotocol is NMEA, is that the Problem?
Calculation Stopps at 370mm Accuracy!?!?
???
Thank you for any Help, Michael
Hi Michael,
The RTCM3 Protocol Out needs to be enabled - on your Base - so it can output corrections:
I hope this helps,
Paul
Thank you Paul,
You write : “The UART2 can be configured for NMEA”.
The OUT is set to NMEA, in the Receiver / Sparkfun 15136!
What im doing wrong??
With the Bluetooth Mate Gold and the same Settings (OUT NMEA),The correction works with 14mm Accuracy!
With BlueSMiRF v2, NO RTK !!
Sounds like it’s not receiving RTCM3 packets correctly.
You should be able to observe ingress via UBX-RXM-RTCM or COR
Perhaps also look at UBX-MON-MSGPP, COMM, IO and RXBUF to understand what’s happening at the interface.
RTCM3 messages must be received complete / intact. They have a 24-bit CRC so won’t tolerate missing, added, or interleaved data in the stream
The question is: can BlueSMiRF v2 , sending NMEA Data to the Sparkfun 16136.
NTRIP APP is sending Correction Data to BlueSMiRF v2 but the Correction wont work.
The Old Bluetooth Mate Gold Can receive the Data!
What can be the Problem?
Hi Michael,
Did you enable RTCM3 in the Protocol In/Out?
Have you checked the baud rate is correct on all ports?
I hope this helps,
Paul
Hi Paul,
With NMEA OUT the Send and Receive of RTK Data works, but the Correction does not get Exacter, minutes after minutes, nothing.
With RTCM3 OUT, it Stopps with the Message : “NTRIP Waiting for GGA from Receiver..”
The Receiver works with RTCM3 IN and NMEA OUT at 115200 Baud an the Bluetooth Mate Gold or Silver.
Something in this BLUE SMiRF v2 Works not exact like the Bluetooth Mate Gold / Silver!
What must i do with the BlueSMiRF v2, that i can use it like the retired Bluetooth Mate Gold / Silver?
Thank you very much, Michael
Hi Michael,
OK - thanks. I understand.
Forgive me for asking the dumb questions: but are you using two BlueSMiRF v2 boards, and have you paired them?
BlueSMiRF v2 will only work with another BlueSMiRF v2. BlueSMiRF v2 will not work with the original Bluetooth Mate Gold / Silver.
I hope this helps,
Paul
Hi Paul,
I Build with this Tutorial: GPS-RTK2 Hookup Guide - SparkFun Learn
a GNSS Receiver :
Arduino MKR ZERO, with qwiic connect to Sparkfun 15136, connected via UART2 to the BlueSMiRF v2 to send and receive the RTK Data via Bluetooth from Smartphone / NTRIP APP.
Thank you very much, Michael
Can you take a few photos of your setup? It will help us troubleshoot the problem.
Can you try a loopback test on your BlueSMiRF? Basically, the BlueSMiRF should be inserted into a breadboard, given 5V and GND, and have a wire connecting TX and RX together. Nothing else should be connected. See these docs for the basic idea. Once assembled, connect to the BlueSMiRF from your phone and open the Serial Bluetooth App for android and connect to the BlueSMiRF. Do you see the connect LED illuminate? Once connected, send a few characters to the BlueSMiRF. They should echo back in the terminal. This will prove the BlueSMiRF is operating. However, it doesn’t guarantee what baud rate the BlueSMiRF is configured at. We’ll get to that later.
Hello Sparky,
All sended Words are comming Back complete! TEST OK!
Green LED illuminates permanent.

I use only an other Board (Arduino MKR ZERO connect with Qwiic) Display 2,8 TFT ILI 9341connected to MKR Zero.
I set the Baudrate in UCenter to 115200.
Thank you very much,
Michael

NO High Precise RTK!
Stopps at ca. 700mm Accuracy…???
