We're using two Blue-NRG2 devices and we would like to implement firmware OTA upgrade without using computer. The goal is to read the binary image file through UART by master device, and then send it to slave device via OTA. Upgrading with BlueNRG GUI works fine, but we couldn't find any example software for master device explaining how to send an image file through radio (only OTA-Server example, which works with radio low-lever driver). Is there any example/manual/solution which we could refer to for writing OTA master software?
