Firmware Version

2.1.4.958d2cf

Description

Attempted to boot with firmware-tlora-t3s3-v1-2.1.4.958d2cf.bin flashed to a new T3S3 V1.1. It appears the radio isn't being detected.

Code: https://github.com/meshtastic/firmware/blob/958d2cf630559c6864da70560957efbf0813af2f/src/main.cpp#L630 Related discussion: https://meshtastic.discourse.group/t/lilygo-t3s3-v1-1/7405/5

This issue has been mentioned on Meshtastic. There might be relevant details there:

GUVWAF commented 1 year ago

Does this board have an actual SX1280 radio (2.4 GHz)? The T3S3 can have different radios.

porkcharsui commented 1 year ago

Board used to produce that log was ordered here: https://www.aliexpress.us/item/3256804440825086.html - specifically SX1280 2.4G With PA model

The silkscreen on the board reads T3S3 V1.1 2021205

caveman99 commented 1 year ago

the radio is initialized with the wrong frequency range. there's code in there that should switch to LORA_24 and reboot in that case, but a recent refactor to support the Sub-GHz chips might have invalidated that check.

GUVWAF commented 1 year ago

@caveman99 Maybe we can do the same as for SX1268 radios? Overriding getFreq() to set it to 2.4GHz when there is no saved_freq yet, such that it initializes on the first attempt.

caveman99 commented 1 year ago

i chose the approach to switch region and reboot because BW setting is different in 2.4GHz too. The slots are not compatible and need to be remapped.

GUVWAF commented 1 year ago

Ah, I see. Actually it is not rebooting now because the error returned by RadioLib is different. -705 is SPI command timeout. Invalid frequency should be -12.

caveman99 commented 1 year ago

yes, saw that as well. maybe we need to compare to rediolib_ok, since 1280 is tried to init last anyway.

mverch67 commented 1 year ago

It could also be a wrong DIO2 / BUSY assignment (e.g. 36 instead of 34). In that case I saw random failures when I tested with the SX1262 chipset. If you look at the variant.h you'll notice that SX1280 has different DIO assignments than SX1262/SX1276 although these three share the same schematics!?

caveman99 commented 1 year ago

it's right according to the scematics (the 1280 uses a module called HPD-17PA) - what intrigues me is that the Interrupt TX example from Lilygo is working with radiolib 5.5.0 but not with 5.7.0 any more.

@GUVWAF indeed good catch - will be fixed in Firmware 2.1.7 or in current Master branch
