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

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
