Transparent transmission between 2 Wemos D1 lite + ES32-868T30D (1W) - message sent but no receive

[Lucamenghini]

Hi Renzo. I have 2 Wemos D1 lite identical to the Wemos on your blog. I connected them exactly as you shown to one (one each) E32-868T30D. I started from your example "sendReceiveTransparentTransmissionE32_TTL_1W". One board is connected to a notebook and the other to another one notebook. I upload to the first and to the second board the skecth below (little bit modified to remove the serialsoftware and use the harwdare on port). The first board starts and I monitoring it by the serial monitor, it appear starting fine and looping for a signal. The second board is used as a transmitter with the same sketch. Reading the code I suppose pressing the reset button on the transmitter the board reboots and send a message: in fact the message "succesfull" is shown but on the serial monitor in the other board no message is shown. Here you are the whole code. Sorry for my english, I'm italian as you but here I wrote in english to support the entire community. Thank you for your support! Best regards

Hi Luca, try to remove pull-up resistor on M0 and M1. And verify that this pin go up and down as needed. Bye Renzo
