ELS31-V: Non-transparent listener doesn't work properly after upgrading from rev B to D(.3.3.0-36343) | Telit Cinterion IoT Developer Community
August 7, 2019 - 10:14pm, 6102 views
Listener is open on service 8. With rev B when everything was working as expected:
1.URC ^SIS: 8,1,x from the module on an incoming connection, where X is a dynamically assigned service.
2. Command AT^SISO=x.
3. Module: URC ^SISR: x,1
4. Then AT^SISR=x,y; and so on.
1. Module doesn't always send URC ^SIS: 8,1,x, or the URC comes with several second delay.
3. URC ^SISR: x,1 never come ( 99% of cases). If URC did come, following exchange works as expected.
Please, advice how this problem can be fixed.
HTTP client seems to work fine.
