Hello,
I am applying Redboard Artemis example ble_freertos_amdtps using IAR , it works fine with nRF-Connect ,
i can connct the Redboard Artemis to it , and in debugging i have found out that there is a response when i ask for data in the file :
atta_ccc.c -> in function : attsCccMainCback

but i really want to know, how to send data via BLE , even 1 Char
anyone has an idea ?

i used the code from https://github.com/paulvha/apollo3 in project ble_amdtp_arduino/Amdtps
and now i can use the incomming data( Mobile->Redboard_artemis) in the function AmdtpReceivePkt in the file amdtp_common
but i still have to figure out how to send from board to Mobile

bi-directional redboard nano to android 8.0 and higher. Has both android source and apk file. Board sends ack and echoes any command sent to it.
