Ebyte Lora UART radios - 433 MHz, Can only use Channels 433.00 and 434.00!

Re: Has anyone worked with e32-433t30d or any products related to EByte Company

I am looking into using these, but, wait... 1MHz channels:
ISM band 433MHz
Channels that you can use:
433.000
434,000
Thats it!
On no!... Why Ebyte?

@projectMarvin As you're really interested in Nordic nRF52840 and nRF52832, I can't prevent myself from suggesting you to have a look at this project where I used a mesh of low power sensors with two types of dongles UART and native USB. https://github.com/nRFMesh/nRF52_Mesh I do not place this project as alternative to MySensors as it does not have the same goal at all (no community, not many sensors), it's very custom, but the advantage is flexibility in case someone wants to be closer to the official nRF SDK, as that's my sole dependency and it is not using softdevices so leaves freedom to use priviledges and inetrrupts as needed. I've been actively looking for standardised method to fulfill low power sensors, mesh network with OTA update. And the way there seems clear but very slow. only nRF52840 supports zigbee, and you need a custom zigbee to MQTT for each network. I have hopes that Thread (OpenThread) will resolve this, but thread is too experimental at the moment and 0 commercial sensors compare to all zigbee sensors available on the market. So I guess, the radio choice for you will depend if you target a commercially supported project which has a development budget or a DIY plan, also how much effort is intended to be spent on custom sensors creation compared to using low cost existing ones. I realised that I can't make DIY sensors cheaper than the existing zigbee one, which breakes the goal of the DIY model unless you do it for learning purpose or for fun. I'm checked the micro python / circuit python, but that's also a slow evolving path where it's not the HW supplier that's worried about porting the drivers but a third party have them limited to some peripherals. Nordic has OTA examples since the very first SDK of nRF5xxx, but it's way challenging to bring it to a seemless user product, just configuring nRF compile flags is quite complicated. I'll keep watching this forum closely and be happ to see a working solution with nRF52xxx, I do have x5 of those nRF52840 usb dongles.

after abit of looking around and testing i think i made it work at least examples are quite responsive without a single disconnect. i had to add some header files and extra bit of code to every sketch so the knows how to use PA/LNA. static void pa_lna_assist(uint32_t gpio_pa_pin, uint32_t gpio_lna_pin) { ret_code_t err_code; static const uint32_t gpio_toggle_ch = 0; static const uint32_t ppi_set_ch = 0; static const uint32_t ppi_clr_ch = 1; // Configure SoftDevice PA/LNA assist ble_opt_t opt; memset(&opt, 0, sizeof(ble_opt_t)); // Common PA/LNA config opt.common_opt.pa_lna.gpiote_ch_id = gpio_toggle_ch; // GPIOTE channel opt.common_opt.pa_lna.ppi_ch_id_clr = ppi_clr_ch; // PPI channel for pin clearing opt.common_opt.pa_lna.ppi_ch_id_set = ppi_set_ch; // PPI channel for pin setting // PA config opt.common_opt.pa_lna.pa_cfg.active_high = 1; // Set the pin to be active high opt.common_opt.pa_lna.pa_cfg.enable = 1; // Enable toggling opt.common_opt.pa_lna.pa_cfg.gpio_pin = gpio_pa_pin; // The GPIO pin to toggle // LNA config opt.common_opt.pa_lna.lna_cfg.active_high = 1; // Set the pin to be active high opt.common_opt.pa_lna.lna_cfg.enable = 1; // Enable toggling opt.common_opt.pa_lna.lna_cfg.gpio_pin = gpio_lna_pin; // The GPIO pin to toggle err_code = sd_ble_opt_set(BLE_COMMON_OPT_PA_LNA, &opt); } in this form i like the ble, without pa not so much. theres just big down side which is nrf52840 definitely not hobbyist friendly. next time i may design a quick nrf52832 pa board (this one has regular QFN package) to test with the same setup and compare the results.

Cool! I have some E78's laying around because they seemed like a nice processor/radio package. But that looked like too big a project for my skills. I'm going to have to dig them out now that there might be a path to get them to work with MySensors.

@cloolalang If you can possibly avoid it, then power line is not the way to go. It turns your whole house wiring into a giant antenna and then some. Your neighbours can also be affected by this as there are currently no requirements for electrical (power) distribution systems to have chokes or filters of any kind.

@viti this forum is in English, please use that. For CO2 sensor you might starting looking at https://www.mysensors.org/build/gas
