Description
I'm currently using an Arduino Opta to advertise some information through the manufacturer's data. Because of this, I need to stop and restart the advertisement of the device quite often. I have noticed that, depending on the sketch and maybe other factors, it works for a while, only to then throw a single advertise error, which is quickly followed by zero successful BLE.advertise() calls after that. This could be an issue with my code, but I can't get any error code other than it failed, and there is not a ton of documentation on possible causes.
The amount of time it takes to fail seems to be random, but after one failure, there is no successful BLE,advertise() call after that. It also seems to be unrelated to connecting to devices, though it may change the average time to first failure. Ending and restarting the BLE stack in the program itself is out of the question because of how long it takes, especially since I have many more characteristics that I removed for code readability in my sample below. I've already guaranteed that the advertisement data all fits within the allotted 31 bytes, and I can confirm so by using NRF Connect and my own BLE scanner app to make sure.
