Which sx127* module ? #3

Closed netmonk closed 2 years ago

netmonk commented 2 years ago

Hello, which SX127* module are you using for dev this library ? i guess hoperf rfm95 or any board with an esp32 and lora module like Liligo.

Why i ask ? Because im looking for support of EbYTES sx1276/78 modules like E19-868M30S Those modules are designed with some added pin like TXEN/RXEN that must be respetively HIGH when sending or receiving. But i never see ESP-IDF library which implement this.

I played with two lora liligo lora32 modules and both basic/pingpong are working fine. Congratulation, now is time to test esp32c3 and Ebyte E19 modules.

Funny the second partner seems to have received some other lora packet (may be my gateway ttn) Screenshot from 2022-02-15 23-34-25

Btw, 60 to 70 ms of back to back time is like 16hz Expresslrs on same hardware reach easely 100hz up to 250hz on 868/915 it can reach 500hz packet rate using 2.4ghz lora modules

Hello. Thank you for your PR.

I used these: https://www.aliexpress.com/item/32911759847.html?spm=a2g0o.9042311.0.0.27424c4dL4D3Cc https://www.aliexpress.com/item/32962551530.html?spm=a2g0o.9042311.0.0.6aa24c4dHXeafK

SX1280 is a bit expensive. So I don't have it. I don't think the SX1280 is compatible with the SX127X. I think the SX1280 has the same specifications as the SX126X.

I am currently ordering the SX1262.

I'm not sure if the E19-868M30S can be used with a pin pitch of 2.54 millimeters. There may be a pitch conversion board for E19-868M30S somewhere.

The EBYTE E28 https://www.ebyte.com/en/product-view-news.html?id=537 is like the Ebyte E22 very small pinout module. I made an expension board for the E22 Module same can be done for the E28 Module : photo_2022-01-12_13-49-42 And sx1280 like sx1262 are new generation transceivers from semtech that's right.

nopnop2002 commented 2 years ago

I made an expension board for the E22 Modul

I want it.....

I think EBYTE should officially support such an expension board.

netmonk commented 2 years ago

Send email to netmonk-at-netmonk dot org with your adress i will send some sample. Beware it’s pin labelled for E22

nopnop2002 commented 2 years ago

Thank you for your offer.

If you sell this on ebay, I will buy it.

https://easyeda.com/dpac/e22-carrier-board You can find the open design here. My proposition was to send you a vrigin pcb board for free. I can also send a mounted board (need to have two in order to test new feature such has SF 5 ) far free. :)

I just checked and E22/E28 are not compatibles in pin design.

Really?

netmonk commented 2 years ago

Yes

nopnop2002 commented 2 years ago

You need Shipping Cost. Are you OK?

netmonk commented 2 years ago

I appreciate you worry about that but don't :) I prefer being paid in answering my stupid question than getting money this has more value to me :)

nopnop2002 commented 2 years ago

I sent mail to you. Thank you again.

netmonk commented 2 years ago

im not sure you click "send" i received nothing

nopnop2002 commented 2 years ago

I made a mistake.

I sent it again.

netmonk commented 2 years ago

Great received :)

nopnop2002 commented 2 years ago

When I receive the extension board, I would like to hear your opinion on which communication module it is worth testing.

I have never used EBYTE's communication module.

netmonk commented 2 years ago

Did you receive anything by airmail ?

nopnop2002 commented 2 years ago

No.

Probably the influence of Ukraine.

netmonk commented 2 years ago

Hello did you receive it ?

nopnop2002 commented 2 years ago

No.
