Dears,
Since one year ago I bought 60 pieces of TTGO Lora 32 devices , over Ali Baba.
Majority of them are working well.
Unfortunately , 7 devices after some time of normal working start to cause a problem and currently are out of order.
On all 7 devices problem is the same – unable to upload the new code (.bin). I treat it with really care. I was uploading and testing some codes and suddenly, it stop allowing me to upload new programs.
Would you be so kind to ,give me advice what should I do?
Thank you in advance
