I am your fan, I believe in you!
For convenience, I hope to provide binary files on github.
No one there?
Hi, alas, I was sleeping ;-)
re: software update over bluetooth This is already implemented, I just have it turned off right now in the app (during alpha)
re: more boards I totally agree. Most boards are easy to port to, though we don't yet have a sx1278 driver (any pull requests would be appreciated). In particular there is an exciting new board this project will support in a few weeks.

Do spill the beans please!

I did a little search around and found this two very promising libraries:
I'm really looking forward to get this supported. The price for a meshtastic compatible device will drop to $10 :exclamation: once this is supported :rocket:
For example some prices from the country of origin:
LORA Board: Ra-02 LoRa Module (SX1278) ~ $3.8
ESP32 Borad: Lolin32 Lite ~ $3.3
GPS Board: NEO-6M GPS Module ~ $3.2
a OLED Display will add another ~$2
@rradar thank you for your note. Since this bug was originally opened we switched to using radiolib so using any radio chipset should now be easy. Currently implemented is sx126x and sx127x.
@MGJ520 Hi Mango - btw - sx1278 would now be super easy to add. alas, I personally don't have a board with that hardware.
Currently implemented is sx126x and sx127x.
I just downloaded the firmwares and there is no "generic" one for sx126x or sx127x. Would it be possible to provide bin files for these?

I would be more than happy to test any alpha/beta/gamma-firmware with my ra-02 lora modules and esp32. Also I have oleds and one gps module to make the most out of it :smiley: Sadly I'm no help with programming or building the firmware itself because I lack the skills for it :grimacing:
Alas. There is no way to provide prebuilt binaries for generic "this radio chip + this esp32" because the connection choices for SPI signals are completely unspecified.
So unfortunately you'd need to build from source after editing configuration.h. Or (in theory) you could just copy the gpio selections for one of existing supported devices and it should then work with that binary. (We probe at runtime for things like screens, GPSes and radios)

I found this short instruction here and cloned already the github repo but I'm a little lost already with the first setting for the frequency. I would need to set EU/433 for the SX1278 (RA-02 Modules) I have but I don't to what value to add in this line:
; HW_VERSION (default US)
The first thing I would try (once I have the right setting for the frequency) would be to build a esp32 with my lora module (SX1278) with the same gpio setup as the supported heltec board and try to use the existing heltec profile. Maybe this could work out :smiley:
OK, I'm all set. I have exactly the same gpio connections between esp32 and the ra-02 lora module (sx1278) despite having gpio 18 connected because the ra-02 module is missing a cs pin.
I didn't set the right frequency yet for my lora board (433mhz), but at least I where able to flash something on the board. The log output on the serial I get is this:
rst:0xc (SW_CPU_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:DIO, clock div:2
load:0x3fff0018,len:4
load:0x3fff001c,len:1044
load:0x40078000,len:8896
load:0x40080400,len:5828
entry 0x400806ac
That looks correct, have you tried seeing if it is then printing out serial messages at 921600 baud (not 115200)?

This was the missing piece, here is the full serial I get:

@rradar It looks like you are almost there. I'd say the next step is to figure out which signal is the chip select signal for your sx1278 board. All 1278s have it - though perhaps by a different name. It is chip select, and I bet that's why the lora init fails with error code -2. Good luck!
So the chip is labled:
RA-02 AI Thinker, ISM: 410-525MHz, PA: +18dBm, LORA/FSK00K LoRa-02, SX1278, 433MHz
This looks like the corresponding product specification. More Resources can be found on the AI Tthinker wiki but it looks to me that there is no more technical data sheet available for the RA-02
I now changed the line ; HW_VERSION (default US)
in platformio.ini to HW_VERSION=EU
and get this serial output:
Connected.

Yep, SS - Slave Select is the same as CS - Chip Select. Looks like you have the correct SPI connection to the Ra-02 now.
Little update.
I have a Lolin32 working with the RA-02 module now. I set HW_VERSION=EU433
in the platformio.ini.
I build another pair of a Lolin32 Lite and a RA-02 module but can't get this flashed. I have the following output in the pio console after the succesful building the firmware (using heltec
):

It might be that board has a serial to USB part that can't run at 921600. Try changing the upload speed in platformio.ini to 115200.

Once again, you are right! I were able to flash it but had no luck with the serial monitor (despite settings this one also to a baud rate of 115200). I added a oled display to see if things work like they should:
Lolin32 Lite + RA-02 + Oled
And it looks good (despite the little distortion of the small oled display with just 128x32 pixels)
My other setup:
Lolin32 + RA-02
Here I can see the serial and I get this:

I tried to get the app running via bluetooth but didn't succeeded so far...
okay sounds like this bug has served its purpose. Closing. If you have other questions we can chat in another issue - or even better the forum.
To be honest, I highly recommend this function that can support modularity. For example, if you only need SMS, then the interface reminds you that you can only use this, and I hope that the APP of this software can be modified, like the chat room, let The interface is better-looking, and can have the same interface as ordinary mobile phone text messages. It can also support the switch between Bluetooth and WIFI connection instead of flashing the firmware through the computer, because it is too troublesome. Secondly, such a Mesh device hopes to pass WIFI. Support multi-person connection, and multiple people share one device.
I highly recommend that it can be used to support more boards, so that it can pass through different boards and different loRa boards, so that it is easier to DIY! For example, this esp32 Espressif and sx1278 (An Xinxin Ra02)
I really hope that everyone can adopt it and act! At the same time, I also hope it will succeed
