Hi Bud!

Love your library. I'm having what I hope is a small problem getting the TFMini-Plus to talk to a Madunio Lora Radio on SoftwareSerial on pins (D4,D5)

It's doing this:

TFMPlus Library Example - 18JUN2020 System reset: Status: TIMEOUT F6 04 60 09 FF 00 00 00 Firmware version: Status: TIMEOUT A3 00 FA 04 B0 41 F8 00 Data-Frame rate: Status: TIMEOUT 00 F5 04 60 09 BF 00 00 Status: HEADER Data: FF 58 99 69 80 08 C0 42 DF Status: HEADER Data: 58 B9 A3 80 1F 08 4B C4 FF Status: HEADER Data: 58 99 A3 80 1F 08 53 C4 FF Status: HEADER Data: 58 99 A3 00 F4 04 60 09 EF Status: HEADER Data: 58 99 A3 00 F5 04 60 09 BF Status: HEADER Data: 58 99 A3 00 F6 04 60 09 FF Status: HEADER Data: 58 99 B3 00 F8 04 B8 41 F0 Status: HEADER

It looks like a serial problem, Zorch. Are you using only one Software Serial port? Are there any pin limitations on the Maduino (change interrupt)? Why D4 and D5? Please send me your code? Thanks, bud at budryerson dot com

Bud I think you're right: I'm using a 3.3V 8MHz Maduino Pro Mini and from what I've read, they can't do 115200 using SoftwareSerial. I need to find a way to lower the baud or change to I2C. Any suggestions which will be lower burden? This is for monitoring water level in our well, which ran dry 10 days ago after a very dry summer here in Nova Scotia.

Lane

I don't have a problem with Software Serial at 115200.  SS does have a problem with RX on certain pins on certain processors.  I do recommend I2C.  Try to keep your wiring short and don't use ribbon cable (conductors side-by-side).

Did you see the 'readme' on the github page?

Keep me posted.

Bud I wanted to let you know that I got everything working, thank you very much. I used a Mega to switch to I2C, which then worked just fine on the Maduino LORA radio / pro mini. I'm now reading the well water level no problem, although I'm not 100% sure that I've got it polling properly. Is there any example code for that? Power consumption is an issue, with little sun in Nova Scotia this time of year... signal-2020-10-13-133042 signal-2020-10-13-133510

That's truly clever. I'm happy to hear that it's working. A larger solar panel is always helpful, especially on cloudy days. Did you make it past the solstice? Best regards, Bud Ryerson San Francisco

Hi Bud,

Thanks for getting back to me. I was able to get the TFmini working again

I brought the system back home to SoCal with me in November because my father decided to drill a new well, obviating the need for monitoring the old well :-).

The project was quite fun; I learned a lot.

Warm regards,

Lane
