in BASIC Stamp
Once again, things are going obsolete...lol. I have been using Linx products with the Basic Stamp for data transfer for a long time. I recently bought the Linx, now CE connectivity, the TRM-433_LT and could not make it work with the stamp. So, has anyone found something that does work with the stamp to exchange data. In my case, it only needs to be one way, but I would take both.....thanks to all

XBee works. You might also look the low-cost LoRa module called the RYRL998.
Other possibilities (ESP32 more future proof?)
ESP-NOW
ZigBEE
Denno doesn't seem to want to give up the BASIC Stamp. I'm building an ESP-01 bridge for the P1 and P2 so that I can connect devices via the ESPNOW protocol. I suppose one could do the same with a BASIC Stamp if the interface in the ESP-01 was set-up to deal with the nature of the BS2.
Yeah, that's what I mean. I have been testing the ESP32 as merely a peripheral. Makes a great Bluetooth device by simply directing the UART to the BT and the code is readily available.
No, I do not want to give up on the Basic Stamp, or the Propmini. I'll start at the beginning, I wanted to learn programming, so with my first computer, the IBM thinkpad, I bought the book QBasic for Dummies while on my sailboat in the Virgin Islands. Then came along Power Basic, and I started learning that...remember the floppy discs?....Anyways, back around 2001'ish, I started with the Basic Stamp. The program was to tell me the simple ON time versus OFF time of my 12 volt refrig system on the boat. And that was with a DELL computer. Ya, I know, moving forward, boat is gone, and now i'm in Michigan (polar vortex now)...and in this house, and car, I presently have, wirelessly, using LINX products, 12 stamps running for outdoor lighting, and temperatures in my house. Yes, Jon, I too monitor temperatures. I even have 2 stamps running in my car wirelessly for transmission and engine temperatures...I have two Propmini's running the thermostats of both the garage furnace and house furnace. I use a wood burner, also, and I monitor the burner temperature using one of Sparkfun's MCP9600 with a stamp. Last but not least, I have a PING sounding my diesel level with a stamp in the tank for my house furness. In general, over the years, the Basic Stamp and the PBASIC, along with PROPBASIC have taught me a lot of programming. So, Jon, I'm not going to give up the stamp. I just bought 5 BS2's off EBAY. I will start using the XBEE's on my next project. And it looks like all the XBEE's are out of stock at Parallax. Presently, I use a Compaq laptop computer....Window's 7.0.....I don't give up things...That's it! BTW, Buck Rogers , did I spell furnace right this time.....
The upshot with the BS2 and with XBee is that you can employ hardware flow control so you don't miss asynchronous messages (if those are allowed in your system). I am also experimenting with LoRa -- it's low cost and long range. I think I mentioned the RYLR998; you can get a module for Amazon for about $12 and they work down to 9600 baud. The down-side from the BS2 perspective is that they send ASCII strings that you have to parse -- this could be a bit tricky with the BS2's limited memory.
