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!

Hi Michael, We have already given you a lot of help. The key issue is that the ZED-F9P UART2 RX byte count is zero. It is not receiving data from the BlueSMiRF. You need to work out why that is happening. I can not explain why the Mate Gold works for you, and the BlueSMiRF v2 does not. But both m…

Sparkfun 15136 is connected with UART2 to BlueSMiRF v2, and also with QWIIC to Arduino MKR Zero this is Connected to ILI9341 here is the Pinout [Michael GNSS PINOUT] Thank you, Michael

A photo would be very helpful. OK. Now we are getting somewhere…! What code is running on the MKR Zero? The BlueSMiRF v2 pins in your diagram are not correct: [image] From left to right, the connections are: GND CTS (No Connect) V (3V3) TO (TX Out) RI (RX In) RTS (No Connect) You …

[Michael GNSS PINOUT] Better? Its connected like your Picture. Thank you, Michael

Much better! :slightly_smiling_face: A photo would be very helpful. What code is running on the MKR Zero? Best, Paul

its to Ugly to make Portraits, ((o; But its exact like the Pinout / Schema Connected. I Built 6 Devices, all with Mate Gold & Silver, since i use BlueSmiRF, the System is not longer working, possible to Build / Work Correct! The Code is my Code. I also pay for the Code-Calculation part, for calcu…

OK Michael, That is as much help as I can give you. Good luck with your project, Paul

Is it Possible to give the code direct to you, not here Online? im now at this Point… [image] Searching for Occasion Bluetooth Mate Gold or Silver Modules Wireless & IoT Because of BIG BlueSMiRF v2 Problems, i need 2-3 Bluetooth Mate Gold or Silver Modules. (o; Than…

You are welcome Michael, I can only help you openly. That way the whole SparkFun community benefits and is able to learn. If you need to keep your code closed source, I understand, but I can not help. Best, Paul

[image] Above, you show the BlueSMiRF attached to 3.3V. Please try powering the BlueSMiRF with a 5V source. I believe we discovered on another post that the BlueSMiRF v2 may need 5V power in order to work correctly.

Hello Sparky, Sparkfun 15136 connected via UART2 to BlueSMiRF v2 ist not ok? No 5V? PAULZC : make it exact the same https://canada1.discourse-cdn.com/sparkfun/original/2X/9/93cfb2340df718b82f690766a9686e320acecfe7.jpeg In your Hookup Guide its Written 3,3V -5V! Hardware Overview - SparkFun BlueS…
