Hi All

I'm looking to start a project using LowRa and the Semtech SX1276 chip.

Just checking in if anyone has any code?

Thanks

Tim

Are you looking for LoRa WAN or custom LoRa? I have a lot of projects with custom LoRa comms at 433 MHz, manufacturing my own (not FCC approved  ) modules too for hobby projects.

Example of one of my early LoRa projects here: http://www.blog.exrockets.com/blog/100-mw-433-mhz-long-range-30-km-gps-tracker-kit/

The aim is to build a custom Type K temperature transmitter network. It will be used in an industrial plant room setting.

The coms will be bursts of TX only every 30 seconds around 35 bytes at a time. Its a broadcast system. If the signal of 1 or 2 nodes is not getting through then they either buy another RX unit or a repeater.

I will need to get full compliance certification EC FCC etc.

Looking to use the Wio-SX1262 LoRa Wireless Module by seed studios.

Custom coms protocol is expected.

433 is probably ideal. 

Is the module you used still available?

Hi Tim,

I designed my own modules and ordered small batch, because the ones sold either don't have a TCXO and LNA or they are too expensive.

I can help with the code, but if FCC certification is required, then I guess you'd need certified LoRa modules?

I created some code for the SX126x transceivers last year, with the help of trastikata, but never used it in anything.

It may give you some ideas how to implement it further, so I have attached it below, and I think it is actually already on the forum, along with posts on it.

They are complex critters, and rather difficult to set up.

I also have a simplistic library that I created for the SX1278 transceiver, back in 2022, if that will help.

However, maybe the Ebyte E220 modules would be better for you Tim, as they have a simple serial interface, and can run at very low current (approx 150uA), and are very simple to operate. I have a library for them as well that I have used in a few applications and they are rather good. Simplistic, but good, and have an excellent range.

Thanks Les

The Ebyte E220 modules sound great. I'm flitting from one to the other at this time. Its very handy to get a serious recommendation.
My aim is to have 10+ year Broadcast of the temp data every 30 mins. All controlled by a XLP pic. Going to serial would be fantastic. It would save so much development time.

I will have to be careful on the power but at least I'm going in the right direction now

Thanks Tim
