Thank you @matsujirushi for responding.
The link that you provided looks like it might help but for me, I will need to read it in English. Is there an English version available ? Sometimes automatic translation makes a mess of the meaning. An expert in two languages would need to make corrections.
I now have my 2nd Wio LTE board, and it has the same problem with battery connector as the first, that is the battery plug will not fit the battery socket despite similar size. Only Seeed can fix this problem, buttthey have not yet acknowledged culpability.
Secondly providing the capability to debug using a com port monitor app and simultaneously have file upload capability (DFU) to load firmware in context of learning and debugging proposed coding solutions.
Thirdly undocumented 3 buttons on the board have functions of boot, reset and xx (unknown) and I think your document addresses that concern, to provide an explanation of how the buttons should be used.
The original issue of Arduino Boards manager for Wio LTE has been addressed by Seeed support who fixed the issue on Git download, including deprecating of the JP version of the board manager.
So as far as I know I am using 1.8.2 Of the Seeed boards manager not the Seeed JP boards manager.
I am wondering if the issue of very poor English language documentation for Wio LTE is caused by them failing to fully translate all of the Japanese documentation. Only some if it. Then failing to mention that original documents are available in Japanese language. Could it be true ?
I am in process to address the issue of virtual com port driver failing after a sketch has been uploaded. I have ordered a 3rd part USB to UART dongle device from Amazon. Intend to connect it to the Grove UART port. It’s annoying Seeed did not include a JTAG pin field on the board. Every other Arduino board has one…
The 3rd party dongle will utilise another com port driver and consistently retain the same USB signature. It will need to be supported by code of course, but is fairly trivial few lines to add defining uart as debug output port.
Thanks and cheers
