A7105 wiring of GIO pins

1 VCC to VDD
2 SCS to TMS (a13 in hardware.ini)
3 GND to Ground
4 SCK to SCK
5 SDIO to MOS
6 GI01 to 9 TXEN
7 GI02 to 8 RXEN
Essentially following this diagram minus 6-9 and 7-8?

I have wired per above but used TCK as TMS is used for my NRF module (working)
1 VCC to VDD
2 SCS to TCK (a14 in hardware.ini)
3 GND to Ground
4 SCK to SCK
5 SDIO to MOS
6 GI01 to 9 TXEN
7 GI02 to 8 RXEN
I have checked with DMM all points to ensure continuity which all tested perfect. I have modified the hardware.ini to ensure I was enabling in A14 and for second line I have =1 to enable power amp. I'm at a loss, the only thing I can think of is I killed it by wiring the old method that is published etc. If there is any diagnostics I can run or test, I'm all ears. Thanks!

If you have checked carefullly your wiring, probably bad A7105 module...

originally I wired using the spreadsheet published here which I assume is the old wiring method, and then I wired via the picture I linked prior, lastly I wired where I added the loops per your indication.
the only thing I haven't tried is removing the NFR.. module (working) and try just the a7105 by itself, I'm seriously thinking about the multimodule or trying to come up with a easier method to clean things up. I was hoping I could test the module somehow such as apply power on TX and probe the pins to see voltage etc., I just don't have that knowledge of what to look for. Is it possible or should I say fairly easy to kill the module by wiring the original (older method) ? I was under the assumption that both would work but it would use less power with newer method etc. I was confused why some diagrams showed GND looped to TXEN but again, not enough knowledge to understand the differences.

You was right, and both will work with the nightly. Only for the last main version, 4.0.1, you have to use the old wiring method.
The reason is, this version is missing some code to manage the GIO pins accordingly.
Since the module did not work even with this, you can assume the module is faulty.

I will try a last ditch effort with removing everything then trying just the a7105 module by itself, if that doesn't work then I'm tossing it and replacing
thanks!

What is your latest nightly? V401-92e1705?
Where can I download your nightly that works with my Devo7e new wiring + nrf24L01-PA-LN and XL7105-D03B module
Thanks
Vincent
