ESP32 lora +oled -Heltec

Post by PANNO »

HI;

I found a Heltec Lora Esp 32 with oled and sx-chip under my Desk.
The Oled works fine with Annex.
I2C.SETUP 4, 15 is setup for the i2c Pins

Is it possible to get Lora Support ?
So we have a Internet Lora Bridge ? ( and Telegram for the Handy while Fishing in the wild ;) )

Even is it possible to change the DAC 1 pin from streaming .here is Lora DIO0.
BTW- these moduls have 8Mb a oled and lora and cost < 10 euro (My mistake :around 16 euro now)

thanks

some links:
should i send you a modul ?

Hi Panno,
are you sure that these modules costs less than 10€ ?
I found that they cost around 15€ (the one that costs less, seems to be without LORA)

HI cicciocb,
unfortunately you are right , maybe i read the price from the modul without lora.
but if you bought an extra module (RYLR896 or so) or an sx1276 from ali ([External Link Removed for Guests]) for 5 euro u get the or higher price.

btw : anybody find a better Price ?

Thanks but, if I understood correctly, the SX1278 should be for China, Southeast Asia, South America and Eastern Europe.
I found this that explains a little bit the differences between the SX1276 and the SX1278

Does someone has already experimented with LoRa ?

I know friends who use it, I follow them on groups on Telegram in any case for Europe the frequencies in use are 433Mhz and 868Mhz the first a little inflated the second less, if it can be useful I can ask you to recommend some modules that they use .

here an example with Oled and 868Mhz

Annex works fine , oled works,(no 2. dac because its used by the sx chip ) and i test it with the heltec arduino examples also.
